Re: subtracting wrfout at different resolutions

You cannot really do this directly, since it is likely that the files will have different dimensions. One possible way would be to interpolate all the data to a common grid using "rcm2rgrid". The other possible way is to "average" the 3x3 grid cells from the fine mesh to obtain the value on the coarse one if your grid ratio is 3 and these grids are part of the same run (and are not a 2-way nest, since the average will be done already).

Hi users,

Has anybody a script to subtract wrfout files at different resolutions?

 
Thanks,
