BREEZE®

3D Analyst

BREEZE 3D AnalystThe ultimate data analyst

• Analyze data through 2D, 3D, and GIS visual displays

• Compare time based data with the time series chart

• View, copy, paste data through the table view

• Extract, transform, and merge multiple datasets

• Export results to Surfer®, Google Earth, and ESRI Shapefiles

• Supports gridded met data, model concentration data, terrain data, and others

• Especially useful when working with 3-dimensional meteorological data such as CALMET

• Generate AVI and Flash movies of time based datasets

Map Display• Create contour maps within a true Geographic Information System

• Overlay results on base maps such as ESRI shapefiles, AutoCAD DXF, and various image formats

• View results through various projections and datums

• Generate AVI and Flash movies of time based datasets

Cross Section Display• Create contour and surface plots of both horizontal and vertical cross sections through 3-dimensional data

Report Display• Summarize both 2D and 3D cross-sectional datasets and provide relevant statistics

Working with Hourly Data

Generating hourly data in AERMODImporting hourly data into 3D Analyst

Generating Hourly Data• Select the Post file option in the Output form in AERMOD.

• Select the post files to generate.

• It is HIGHLY recommended to select “Binary” as the output file format.

Importing Hourly Data• When opening an AERMOD archive (amz) file in 3D Analyst, a “Select data” dialog is displayed.

• Select the “Post data (hourly)”option, and the desired dataset to import.

• A “Time Period” dialog will also be displayed to select the hours of data to import.

Block Averages• This process will extract new 3-hour block average dataset from the existing hourly dataset.

• The Automated extraction method is the best option to easily generate block and rolling averages from an hourly dataset

Block Averages• Contours in Map display of 3-hour block average containing hours 12, 13, and 14.

Custom Averages• User defined extraction method – USE WITH CAUTION!

Custom Averages• Contours in Map display of custom averaging period from 02:15 to 04:30.

Transformation• Apply transformations to data while viewing within 3D Analyst

• Transformations are temporary and do not affect the original data

TransformationOriginal results at 1996/01/01 12:00. Scaled and translated results at

1996/01/01 12:00.

Percentiles• This process will extract a new dataset with 99, 98, and 97th percentiles from the existing hourly dataset.

Percentiles• 97th percentile results for 31 day period.

Percentiles• 97th percentile results for 31 day period.

Highs• This process will extract a new dataset with 1st, 2nd, 4th, and 16th highs from the existing hourly dataset.

Highs• 4th high results for 31 day period.

Highs• 4th high results for 31 day period.

Thresholds• This process will extract a new dataset of 1, 10, 100, and 1000 ug/m**3 thresholds from the existing hourly dataset.

• Results consist of a zero or one at each receptor for each time period.

• A value of zero indicates the concentration at that receptor/time was below the threshold.

• A value of one indicates the concentration at that receptor/time was equal to or above the threshold.

Thresholds• Receptors exceeding the 10 ug/m**3 threshold at 1996/01/01 12:00.

Thresholds• Contours of 10 ug/m**3 threshold value.

Exceedances• This process will extract a new dataset of 1, 10, 100, and 1000 ug/m**3 exceedances from the existing hourly dataset.

• Results consist of the total number of exceedances at each receptor for all time periods.

Exceedances• Total exceedances over 100 ug/m**3 for the entire period.

Exceedances• Contours of 100 ug/m**3 exceedances.

Downwash Analyst Webinar

Learn how BREEZE Downwash Analyst can be used to visually: Observe how the EPA's BPIP-PRM processor computes GEP stack heights and building profile parameters Identify all the buildings that influence each stack source Examine the building geometry and wind direction that produce the largest GEP height for each stack Analyze the conditions (single-tier, tier-group, wind direction, and structure influence zone) that produce each building profile Display AERMOD-computed PRIME plumes (with their corresponding near/far wake boundaries) resulting from building profiles
