Didn’t you hear? Its abbreviation Tuesday. The Weather Research Forecast [WRF] Development Test Center [DTC] has announced the 2.0 release of the Community Gridpoint Statistical Interpolation (GSI) data assimilation system. The 2.0 release adds significant capability beyond the 1.0 release, including:
- Assimilating tropical storm pseudo sea-level pressure observations
- Assimilating NOAA-19 HIRS/4 and AMSU-A brightness temperature observations
- Assimilating RARS 1B data
- Assimilating NOAA-18 SBUV/2 and AURA OMI Ozone observations. Monitor NOAA-19 and METOP-2 GOME Ozone observations
- Assimilating EUMETSAT-9 Atmospheric Motion Vectors
- Using uniform thinning mesh for brightness temperature data
- Improving assimilation of GPS radio occultation data (forward operator, QC procedures, observation error tuning)
- Adding dry mass pressure constraint
- Using NASA Goddard Modeling and Assimilation Office/EMC merged code including hooks for 4DVAR and Observation Sensitivity
- Updating background error covariance file
Supported build platforms include Linux [multiple flavors], IBM [AIX], Mac OSX, and SGI Altix [via Intel v10 compilers]. For more info on the release, check out the website here.
