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 On Thu, May 2, 2013 at 12:59 AM, Leo Kris Palao <lk.pa...@gmail.com> wrote: > Hi *QGIS users*, > > I am working with daily rainfall raster dataset of one decade acquired > from *TRMM*.
