I recently developed a free software MeteoInfo for meteorological data view and analysis. I hope it could be useful to you. Any comment and suggestion are welcome.

MeteoInfo is a free software designed to view and analysis the
meteorological data interactively. It is not just a plotting package,
attribute data were also created when creating meteo-data figure. GIS
conceptions were used in this software. Most GIS functions were
developed from ground level (not depend on any other GIS component or
library). It was developed with C# in Microsoft .Net environment.
MeteInfo could be run in Windows with .NetFramework 3.5, or in UNIX
like systems with Mono.
