Split temperature data in two NetCDF

[Francis]

Hi,

I have temperature data from 2012 to 2016 inside a NetCDF file and 2016 to 2021 inside another. Unfortunately, the grid system used in those two files are different so I cannot merge them without processing them.

If I use two griddedforcing in my .rvt file for the temperature, how will Raven process the data? Will it read them as continuous data? If no, should I warm start the model with the data from 2012 to 2016 or should I process the NetCDF files to merge them?

Thank you!
Francis

Hi Francis

Unfortunately you will need to merge them into one grid to provide the input for that forcing. If you had different forcings in different grids they could be provided separately with different grid weights etc., but for the same forcing they will need to come from the same netcdf file.

However, this can be done with something like cdo tools to remap one grid to the grid of another without hopefully too much trouble.

Let me know if you have any other questions.
