Meteorology

GRASS used together with R-stats provides a powerful toolset to analyse meteorological time series and to perform spatio-temporal interpolation.

• Importing GRIB data

• Weather symbols to use with GRASS display and cartography modules

• Work in progress: d.barb: Displays wind barbs or variable length straw diagrams given either two raster maps, or vector point data. Like d.rast.arrow, input data is given as magnitude and direction. (Hamish)

• r.in.gdal - useful for importing raster data from very many source data formats.

• r.series - useful for time series analysis of raster data.

• v.surf.rst - useful for 2D spline interpolation between sparse data points.

• v.vol.rst - useful for 3D spline interpolation between sparse data points. See the Slovakia 3D precipitation voxel isosurfaces screenshot on the visualization screenshots page. Tutorial can be found in the grass book.(??)
