New Features

Topic Feature Description

Install Compatibility with Windows 8, 32-Bit and 64-Bit

AERMOD View Version 8.1 is compatible with Microsoft Windows 8, 32-bit

and 64-bit versions.

AERMOD MPI (Parallel Version) requires the installation of MPICH2, which

requires that .NET Framework 3.5 is installed in your computer. As

opposed to Windows 7 and XP, Windows 8 does not automatically install

.NET Framework 3.5. The user must manually select it before installing

MPICH2 1.4.1. Instructions are provided in the AERMOD View Installation

Notes.

Models Latest Releases of US EPA Models Available

The following US EPA Models were released since Dec/2012 and are

incorporated into AERMOD View Version 8.1:

1. AERMOD Model 12345 (Released Dec 2012)

2. AERMET Model 12345 (Released Dec 2012)

3. AERSURFACE Model 13016 (Released Jan 2013)






AERMOD

MPI

New Version of Lakes AERMOD MPI 12345 (Parallel Version)

A new version of the Lakes AERMOD MPI for the US EPA Model Version

12345 is now available (AERMOD_MPI_Lakes_12345.exe). You can

specify to use this model under the Preferences dialog.

Note: AERMOD_MPI_LAKES_12345.EXE or AERMOD_MPI_LAKES.EXE will

run the latest version of the AERMOD model (12345) in parallel mode

using up to a maximum of 8 cores.

Control

Pathway

New Non-Default Options in Control Pathway

New Non-Default BETA options have been added to the Control Pathway

supporting the new options introduced in the US EPA AERMOD Model

12345. These options address model performance concerns in low wind

speed conditions:

METHOD STABLEBL ADJ_U*: adjust surface friction velocity.

LOWWIND1: increases minimum horizontal turbulence and turns off

horizontal plume meander.

LOWWIND2: increases minimum horizontal turbulence and

incorporates a modified meander component.

Users can input a user-specified minimum sigma-v, minimum wind speed,

and maximum meander factor in conjunction with the LOWWIND1 and

LOWWIND2 options.

An additional option was introduced that allows users to specify that input

wind speeds are vector means not scalar means.






Source

Pathway

New Line Source Type Introduced

A new source type, LINE, was introduced in the US EPA AERMOD Model

12345. This new LINE source is an alternative to the current AREA source

type for rectangular sources.

The LINE source type, specified as 1 line segment with start/end points

and width, utilizes the same routines as the AREA source type, and will

give identical results for equivalent source inputs.

A graphical tool was implemented in AERMOD View for this new source

type.

Terrain

Processor

Updates to the Download of NED Terrain Data

The feature to download NED terrain data from the USGS site, introduced

in AERMOD View Version 8, was updated.

Beginning December 18, 2012, the USGS

National Map Server no longer offers download

of NED data in GeoTIFF format, which is the

format accepted by AERMAP. NED 1 and 1/3

arc-second data is now only available through

1- degree tiles in ArcGrid and GridFloat formats.

Lakes Environmental incorporated in AERMOD View 8.1 a seamless

conversion of downloaded 1-degree GridFloat tiles into the GeoTIFF

format.

Note: Support for non-CONUS areas (Hawaii, Alaska, and Puerto Rico)

was also implemented.






Met

Pathway

Version and Processing Parameters Shown

Under the Met Pathway, the Version number of the specified Surface Met

file (*.SFC) will be displayed for your verification (e.g., Version 12345).

This version corresponds to the US EPA AERMET version that was used to

preprocess the met file.

If you preprocessed your met data using the new AERMET options

introduced in version 12345 (THRESH_1MIN and ADJ_U*), then these

options will also be indicated after the version number.

General Options to Undo/Redo Changes

You can now Undo or Redo Move/Rotate/Resize changes to graphical model elements (e.g. annotations) using the Edit | Undo

and Edit |Redo options.

Import/

Export Updated Functionality for Import/Export of Excel Files

Previous versions of AERMOD View required that you have Microsoft Excel installed in your computer in order to use the

Import/Export from Excel file (*.XLS) functionality. Starting with AERMOD View 8.1, you no longer need to have Excel installed on your machine.






Export Support for Excel *.XLSX Format

The number of columns supported for the import/export of source

parameters (specifically related to X,Y coordinates for polygonal area

sources with many vertices) was limited to 256 columns which is a

limitation of Excel 2003 (*.xls).

In AERMOD View 8.1 during export you can select to save the data as an

MS Excel 2007 Format (*.xlsx) which allows for more than 256 columns.

Base Maps Grayscale Option for Tile Maps

You can now select to import Tile Maps in grayscale instead of in color.

New Features & Fixed Issues


Base Maps Automated Download of Worldwide Geo-Referenced Base Maps

The Import Tile Maps feature allows users to import imagery from

various online resources. The program comes loaded with 6 different Map

Servers which range from road maps (e.g., OpenStreetMap, MapQuest

Streets) to Satellite and Aerial photography (e.g., MapQuest Satellite,

CloudMade Maps). Additional Map Servers can be added by the user.

Simple Steps:

Step 1: Create your AERMOD View project.

Step 2: Select Import | Tile Maps menu option.

Step 3: Select Map type (e.g., OpenStreetMap) and click OK.






Downloaded imagery is stored locally. Check the File | Preferences |

World Map Settings to add Proxy Server details.

NOTE: The Import Tile Maps feature is only available for users with

current maintenance. If you are receiving this update as part of your

maintenance, once your maintenance expires, you will no longer have

access to this feature.

Models New AERMAP MPI Executable (8-Core)

A parallelized version of the AERMAP executable (11103) has been added

to AERMOD View. AERMAP MPI will work on up to 8 processors, and it

significantly reduces runtimes when processing elevation data especially

with complex file formats like the 10-meter National Elevation Dataset

(NED) tiles.

See the Getting Started – AERMOD MPI & AERMAP MPI document,

available in the update site, for further instructions.






Import

Buildings

from DXF

Additional Options for Importing Buildings from DXF

Layer to Import: Import more than one layer containing buildings.

Offset Option: Allows you to shift your buildings in the project

domain (e.g. convert a local Cartesian coordinate system to

UTM).

Base Maps Improved Method of Importing Multiple Georeferenced Base Maps

Using this feature allows you to search for multiple base maps, which

already contain georeferenced world files, located in the same folder and

import them either as a single layer or as separate maps.






Base Maps Import Raster Images

You can now import any supported raster image file (e.g., BMP, JPEG,

TIFF, etc.) using the same option in the menu.

Tools New LEADPOST Executable in LEAD Post-Processor

AERMOD View now uses the latest version of LEADPOST (12114) in the

LEAD Post-Processor Utility. LEADPOST Version 12114 was released by

the US EPA on April 2012.

Source

Pathway

Input Total Line Emission Rate for Line Area Sources

The emission rate for the Line Area source can now be input as the total

emission rate for the entire line instead of the emission rate per unit area.

The area sources along the line must be generated before the total line

emission rate can be entered.

Source

Pathway

Line Volume Source Emission Rates – Issue Fixed

Fixed issue in which a fatal error was generated if a line source emission

rate was an integer instead of a real number (e.g., 1E-5 instead of 1.0E-5

or 0.00001). Program now creates a real value.






Terrain

Processor

Automatic Download of NED Terrain Data

Users can now automatically download USGS National Elevation

Dataset terrain data files for projects located in the United States.

Select the WebGIS button and choose either 1/3 arc-second (~10

meter) or 1 arc-second (~30 meter) resolution.

NOTE: This feature is only available for users with current

maintenance. If you are receiving this update as part of your

maintenance, once your maintenance expires, you will no longer

have access to this feature.






Terrain

Processor

AERMAP Domain Selection

Consistent with the latest AERMAP executable release by the U.S.

EPA, the Terrain Processor defaults to unspecified domain extents

when running AERMAP. With this option enabled, AERMAP will

process the entire terrain file when calculating elevations and hill

height scales.

Terrain

Processor

Buffer for WebGIS Terrain Downloads

All maps downloaded from the WebGIS button will include a 5% buffer

region. The buffer will help protect projects located close to edges of

terrain files that their project domain will be covered.

Terrain

Processor

Extended Support for Large Domains

Internal changes were made to reduce incidence of memory errors (e.g.,

“Table is full”) which prevented the Terrain Processor from handling

data which covered a large domain or when the number and resolution of

terrain files was very large.






Terrain

Processor

Optimized Elevation Import

The process for importing elevations to model objects, after AERMAP has

been run, was optimized for faster processing times. The options under

the Import Elevations/Hill Heights dialog were simplified for easy of use.

Details Additional Warnings in Details

AERMOD View will now warn you if a Source and/or Building have a base

elevation of zero while receptors do not.






Graphical

Options

Default Contour Shade Style set to Transparent

Results contours will now default to the Transparent Shade Style after

the model is run. This change makes all lower-layer overlays (e.g., base

maps) easier to see beneath the results contours. Also, the Alpha Blend

option was renamed Transparent option for easy understanding.

Graphical

Options

New Default Level Options for Concentration Contours

Contour levels are now set using the Natural value distribution algorithm

by default. The Natural algorithm creates rounded level values (e.g., 10,

20, 50, 100, 200, etc.).

The default minimum value is now defined as the maximum between the

plot minimum value and the plot maximum value divided by 100.






Annotation

Toolbar

Transparency Option for Annotations

A transparency level can be set for all annotation objects.

Annotations Last Selected Annotation Settings

Last selected settings for the Annotation tools will now be saved. These

settings will be applied globally – the changes made in one project will be

applied to annotations made in the next project until changed again.

Contour

Legend

Emission Output Labels on Legend

Resolved a problem with deposition plots where the contour legend did

not display the user-specified emission output unit.






Order Met

the interface.

Multi-

Chemical

Utility

Multi-Chemical Utility Now Generates Plotfiles with Scientific

Notation for Very Small Values

The Multi-Chemical Utility can now handle again very small concentration

values. In AERMOD View Version 7.6, these values were being written as

zeros (e.g., 0.00000). In this release, if very small values are detected

(e.g., 0.0000023), the concentration/deposition results in the plotfile will

be automatically written all in scientific notation.

POST View Additional Features Implemented in POST View

The following menu options/features were introduced in POST View:

Import Tile Maps (current maintenance only)

Import Raster Images using one menu option

Print to PDF option under the File menu

Transparency options for Annotation tools

large. The Select All option is now available at the top of the menu list.






Run Generate Run Status Log Files

The status of the several US EPA executables runs is re-directed to the

AERMOD View Run Status window. Now the user has the option to save

the contents of this Run Status into a Log file. The log files will be

automatically saved in the project folder:

ProjectName_ModelName.log (Example Tutorial_AERMOD.log)

This option can be set to inactive in the Preferences dialog –

Appearance panel as seen in image below.

Output Split Exceedance Count based on Flagpole Heights

The exceedance plotfile can now differentiate exceedances for receptor

points at the same X, Y location that have different Flagpole Heights.

Now receptors at the same location but different flagpole heights get

additional counts instead of one combined count.

AERMAP Warning to Run AERMAP If Default Flagpole Height Changed

AERMOD View now gives a Warning message for the user to run AERMAP

again in case the user has changed the default value for the Flagpole

Height after already having run the AERMAP model. In this case, the user

must run AERMAP again before running the AERMOD model.

Import Importing AERMOD Input Files with Julian Day Ranges in

Meteorology Options

When importing AERMOD input files to AERMOD View Version 7.4, the

program ignored the ME DAYRANGE parameter correctly if individual days

were specified using Julian day notation instead of MM/DD.

This has been fixed in AERMOD View Version 7.5.

Import Importing Projects which Contain Spaces in the Project Name

AERMOD View Version 7.3 introduced project names greater than 8-

characters and containing spaces.

An issue was found in Version 7.4 when attempting to import some

AERMOD input files which used double quotes around referenced project

files. This issue has been resolved in Version 7.5.

Receptor

Pathway

AERMOD Failed to Run for Project Names Containing Spaces

In AERMOD View, the default name for the receptor output file (*.ROU)

and source output file (*.SOU) files produced by AERMAP is the project

name.

With the introduction of project names greater than 8-characters and

containing spaces, starting in AERMOD View Version 7.3, an issue was

found in importing the .ROU file to the AERMOD input file which prevented

the model from running successfully. This issue has been resolved by

using double quotes when specifying file names with space.

Source

Pathway

Changing Source Type to Line Area Source

An issue was discovered in AERMOD View Version 7.4 when users tried to

manually change the source type from line volume to line area source

type. Parameters associated with the source (e.g., deposition, source

group assignments) would use incorrect source IDs for the automatically-

generated sources along the line’s path resulting in unsuccessful model

runs. This issue has been resolved in Version 7.5.

AERMAP AERMAP Failed to Run for Projects Names Containing Spaces

In AERMOD View, the default name for the receptor output file (*.ROU)

and source output file (*.SOU) files produced by AERMAP is the project

name.

With the introduction of project names greater than 8-characters and

containing spaces, starting in AERMOD View Version 7.3, an issue was

found when trying to run the AERMAP model for projects names with

spaces. This issue has been resolved by using double quotes when

specifying file names with space.

Variable

Emissions

Variable Emissions for Line Area Sources

The Line Area source introduced in AERMOD View Version 7.3 did not

support the specification of variable emissions. This option is now

available in AERMOD View Version 7.4.

Import Importing Source IDs Greater than 8 Characters

Now you can import sources with IDs greater than 8 characters and up to

12 characters long from an xls, csv, or tab file.

In AERMOD View Version 7.3, the message “Error of database access!"

was being displayed in case any source IDs were greater than 8

characters when sources were being imported from a csv file.

The support for source IDs up to 12-characters long was introduced with

the release of the US EPA AERMOD model version 11103. Please note

Pathway

New Source Type “Line Area Source” Introduced

The line area source tool is a new feature of the AERMOD View

interface. This source type creates a series of area sources along a user-

defined line segments.






Utility MAKEMET Utility

The MAKEMET Utility allows you to easily specify the parameters

necessary to run the US EPA MAKEMET program. This program generates

a matrix of meteorological conditions, in the form of AERMET-ready

surface (*.SFC) and profile (*.PFL) files, based on user-specified surface

characteristics, ambient temperatures, minimum wind speed, and

anemometer height.

You have access to this utility by selecting Tools |MAKEMET Utility...

from the AERMOD View and AERMET View menu.

The screening met files generated by MAKEMET (*.SFC and *.PFL) can be

used to run the AERMOD model in screening mode by selecting in

projects.

Percentile

Option

Select Interpolate Values or Nearest Discrete Value for Percentile

Option

You can now select if the percentile plotfiles results should be interpolated

(current method) or if instead the nearest value should be selected.

Graphical

Options

Wrong Label Unit for Exceedance Files

A wrong unit label (ug/m3) was being assigned to the exceedance plotfiles

instead of the correct one (COUNT). Exceedance plotfiles are generated

by AERMOD View from the MAXIFILEs generated by the US EPA models.

MAXIFILE output is given in terms of ug/m3 but the exceedance plotfiles

give the number of times the specified threshold is exceeded (COUNT).

This issue has been resolved.






Import Import Building Downwash Data from Model Input Files

Under the Source Pathway – Building Downwash page, you can now

also import building downwash results from AERMOD, ISCST3, or ISC-

PRIME input files in addition to the existing option to import data from

BPIP output files.

Export Flare Sources Now Being Exported to Excel

Flare sources were not being exported to the Excel format. This issue has

been corrected.

Error

Messages

Problem with the Use of Double-Quotes for ISCST3/ISC-PRIME

Input Files

In AERMOD View version 7.0 and 7.1, double-quotes for file paths

containing spaces were introduced for the AERMOD model. Erroneously,

this new notation was also introduced for the ISCST3 and ISC-PRIME

input files generated by AERMOD View. The ISCST3 and ISC-PRIME

models do no support this new notation.

Double-quotes are no longer being used by AERMOD View when

generating the input files for ISCST3 and ISC-PRIME models.

Example: If a SAMSON file is provided for one of the NWS stations which

are present under the ASOS station list (see previous topic) and the year

of the SAMSON file is prior to 1961 or beyond 1990, then AERMET will set

all cloud cover values for the surface output file (*.SFC) as missing (99).

This SFC file will not be appropriate for use with the AERMOD model.

For stations IDs not found in the ASOS list (e.g., 99999, 66666, etc.), a
