Build HistoryBuild History RSA LAPS/MM5 V1: Dec 2001

– Initial installation at WR

RSA LAPS/MM5 V2: Aug 2002– Initial installation at ER

– Included “easy” install CD, provided to LMMS

RSA LAPS/MM5 V2.1: July 2003– Delivered to LMMS on CD

RSA LAPS/MM5 V2.2: July 2004– Delivered to LMMS on CD

RSA LAPS/MM5 V3.0: September 2005– Delivered to LMMS on CD

12

Current StatusCurrent Status

Current RSA status– Fully adapted to AS 2.1 OS– Testing criteria delivered to LM

Current ActivitiesCurrent Activities

Current activities– Working periodically with LM on server OS

upgrade tests

Test / Build procedureTest / Build procedurePrevious CD’s “updated” existing installation

– Previous software version in place on machine– CD contained somewhat limited software changes

New “wipe-clean” installation needed?– recent GSD server tests erased existing software– full install needed on blank system– Existing CD requires add-on instructions and patches– More complete software/data proposed for CD

15

Test / Build procedureTest / Build procedureSame system now used at GSD for staging CD and

testing CD installation– change from past procedures– also requires “wipe-clean” of machine– down time during testing– full backup thus needed to restore developmental

software after testing– acquire separate machines for software staging and

installation testing?

Recent IssuesRecent Issues

FSL access to RTAMPS dataComplete real-time data preferable to partial archived

– Helps evaluate spatial distribution and QC performanceAnalysis bulls-eyes and QC

– Land/sea weighting function adjusted to address thisNOAAPORT buoy data timing

Interface to GOES Sounder on NOAAPORT?

30-min LAPS cycle

Narrowband RadarNarrowband Radar

Narrowband (Level-III) radar– may not be getting into LAPS at the ranges– AWIPS to LAPS NetCDF converter needs checkout– plan to retest radar processing on shadow system

19

Soil Moisture (next steps)Soil Moisture (next steps)Identify soil data in RSA database

– LAPS now reads TOWER (overall) soil moisture (if available)

– what other range soil observations exist? – NetCDF data format?

What LAPS ingest improvements are needed?Develop soil data analysis techniques

– overall Soil Moisture currently in Big File– add other (multi-layer) soil related fields– blend in-situ data with radar-derived precip

Initialize forecast with LAPS soil analyses

20

VerificationVerification

Verification Package– Surface observations vs. MM5 forecast– Requires MySQL database– Interactive query capability

Command line or web based User customization options

– Being set up on development system for 10-km MM5 grids

– Still testing interface scripts

21

VerificationVerification

Verification package– Can run on more powerful headnode

MySQL database Verify state variables Apache web server running on Range headnodes for

interactive displays Forecasters use web browser to access verification

info Product reliability monitor will be included

22

Grid SizeGrid Size

Should analysis/model grids be enlarged?– More computer power may be needed for this

23

Recommended ScheduleRecommended Schedule

Deliver LAPS/RSA v4.0 – Jan 2007?– Incorporate WRF forecast model– 30-minute analysis cycle– capability of “wipe-clean” install– soil moisture improvements?– improved verification package

24

SummarySummary

July build on-track– Improved LAPS analysis with additional local

data and improved algorithms– Better forecasts from new microphysics, better

SST

Apache server installed for verification display at ranges

Continue planning for future
