You should use the raster calculator to do any calculations on rasters, or some of the tools in processing. But your use case seems a bit complicated - perhaps there is a hydrological plugin or processing algorithm that can help.
Have you tried loading the file in QGIS? But be aware that netcdf files with many variables are a bit tricky - each variable is a subdataset, which is treated as a separate file. See the gdal netcdf page for more details [1]. You could translate them to individual files in another format like gtiff using gdal: gdal_translate -of gtiff -sds in.nc out [1] http://www.gdal.org/frmt_netcdf.html On Mon, Apr 14, 2014 at 1:28 PM, Steve Friedman <[email protected]> wrote: > No. The Netcdf file has 20+ variables.
