The CROCO manual says that with the cpp option, ONLINE, CROCO will interpolate forcing files to CROCO grids online. I assume this is the same function as the Rutgers’ ROMS saving storage as CROCO does not need the forcing files interpolated to CROCO grids. I want to use it to save some storage as interpolated forcing file (0.25 deg to <1 km) is rather big and wastes storage space.
However, there is no instruction on how to prepare the “native files”. Can someone show me the metadata of the forcing netcdf (the output of ncdump -h)? I am trying to use ERA5 on this. I’ve already downloaded ERA5 data, but I think the “native files” are not the ones I downloaded.
Read native files and perform
online interpolation on CROCO | grid
(default cubic interpolation)
Thanks in advance.
