Elevation for Gridded Data netcdf
Posted: Fri Jul 09, 2021 3:38 am
Hello, i am using a netcdf file for precipitation, temperature and wind forcings for my model, all have the same resolution of 5 [km] approximately. I am using a process of sublimation and i would like to generate orographic corrections of wind speed . I don't know how to assign elevation to grid of netcdf archive in Raven and i get the following advisory on my raven_error.txt file:
" ADVISORY : Since no elevation data are in NetCDF file D:/ModeloH/DELSA793/WindSpeed_SIERRA_WDATA///inputs/Windhuascohr.nc, all orographic corrections for WIND_VEL will be disabled unless :StationElevations or :StationElevationsByIdx command is present. "
Then when i see in Forcingfunctions.csv file, wind speed is zero for all period of simulation.
How can i assign elevation to each grid? I have to put this data in the netcdf or in the rvt file? Can i assign elevations to each grid like the process of assignation to a meteorological gauge in Raven (page 164 of Raven Manual)?
Thanks a lot,
Cheers
