RSA LAPS Data SourcesRSA LAPS Data Sources
National Data (NOAAPORT SBN Feed)– Eta (Grids 211, 212, and 215)– Regional narrowband WSR-88D reflectivity– GOES imagery (Vis, SWIR, 2 LWIR)– MDCARS– RAOBs– METARs/Ship Reports/Buoys– National Profiler Network

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
17
Recent Issues (cont)Recent Issues (cont)
Additional SST testing
Ingest /Analysis of Soil sensor data
Interface to GOES Sounder on NOAAPORT?
30-min LAPS cycle
18
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
