Hi Markus, hi all, thanks for your help!
I just uploaded two example data files (modelled precipitation at 0.11 degrees) of EURO CORDEX data with rotated-pole grids to play with: https://we.tl/t-ZaZWaPyIaA Attached also a description of the EURO CORDEX data and the grid domains. Typically such data are processed and manipulated with the CDO toolset (Climate Data Operators, https://code.mpimet.mpg.de/projects/cdo, see attached in the shared folder). CDO can easily load the netcdf data and even remap it to other grids (although I am not sure how that works exactly); So maybe another way (if rotated pole is not possible with GRASS/gdal) I could try to transform using CDO and then import into a GRASS location.... /Johannes On Mon, Oct 21, 2019 at 10:39 PM Markus Neteler <[email protected]> wrote: > Hi Johannes, > > On Fri, Oct 18, 2019 at 2:57 PM Johannes Radinger > <[email protected]> wrote: > > > > Hi all, > > > > I was wondering if anybody is also working with CORDEX data (Regionally > downscaled climate data - Europe) that are provided via the ESGF platforms > as netcdf files? > > > > I want to import such files in GRASS but first want to create a location > with the projection of these data.
