[Qgis-user] plugin for processing multiple raster files

[Etienne Tourigny]

Hi,

I am not sure you need GIS tools (such as QGIS) to do this kind of thing,
which is fairly routin in the meteorological/climate research field.

My advice would be to convert the TRMM data to a single netcdf file (which
is much more suited for temporal + spatial datasets), and then process the
data using command-line tools like CDO or NCO. In my experience this could
be done with just a few commands.

cdo: https://code.zmaw.de/projects/cdo
nco: nco.sourceforge.net/

BTW in which format did you get the TRMM data? most likely netcdf or hdf,,,

let me know privately if you need a bit more help

cheers
Etienne
