LAPS Analysis Software

• by Steve Albers

Basic Solution

• LAPS coupled with MM5 NWP model
• Use diabatic initialization (hot start)
• Utilize parallel code on Linux cluster
• Integrate with AWIPS in a modular fashion

• 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 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 Status

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

13
Current Activities

• Current activities
• Working periodically with LM on server OS upgrade
  tests

14
Test / Build procedure

• Previous CDs 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 procedure

• Same 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?

16
Recent Issues

• FSL access to RTAMPS data
• Complete real-time data preferable to partial
  archived
• Helps evaluate spatial distribution and QC
  performance
• Analysis bulls-eyes and QC
• Land/sea weighting function adjusted to address
  this
• NOAAPORT buoy data timing

17
Recent Issues (cont)

• Additional SST testing
• Ingest /Analysis of Soil sensor data
• Interface to GOES Sounder on NOAAPORT?
• 30-min LAPS cycle

18
Narrowband 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)

• 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
Verification

• 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
Verification

• 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 Size

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

23
Recommended 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
Summary

• 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
