MADIS WRF-Var Interface
October 2009: The current observation pre-processor package that's part of the Weather Research and Forecasting (WRF) variational data assimilation package includes a converter that will convert some of the MADIS datasets into the little_r text format, then the converted data will be sent to the variational analysis. MADIS datasets that are currently supported include aircraft, ASOS and other METAR, Canadian SAO's, maritime (including ships, buoys and C-MAN stations), radiosondes, aircraft, and GOES satellite winds.
The WRF-Var group has a new version of a direct-to-MADIS interface, which will add support for mesonet and profiler data, in their testing system, but have not announced plans for incorporating this into a version release.
August 2010: The little_r converter now works with the mesonet data.
