Meteorology

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


d.rast.arrow at work
  • r.series - useful for time series analysis of raster data.
  • v.surf.rst - useful for 2D spline interpolation between sparse data points.


Conventions

Wind meteo data usually follow a convention different from the GRASS one. First, the wind direction expresses the direction which wind blows FROM and not TO. Second, the convention on directions differs from the one adopted by GRASS (for aspect, flow direction, etc.).
