Hi,
I am applying perturbations to ERA5 SSTs for my WRF simulations. Currently, I have a netCDF file of my SST fields that I will be putting in my WRF simulation that is 383 x 292 x 217 (lon x lat x time). I used ERA5 SST data and applied my perturbations to it at each lat lon point for the duration of my simulation (217 hours), so they are resolved at 0.25 x 0.25 degrees. I need to edit the SSTs in my metgrid files to apply my perturbations, so I want to replace the SST field in the metgrid file with my SST field. To do this, I need to regrid my SST field onto my WRF SST field which is 340 x 330, 27 km resolution for the outermost domain. (I also have nested domains at 9km and 3km resolution, but for now I am just trying to figure this out on one domain). How can I regrid my SSTs to the WRF domain in my metgrid files? I am not very familiar with NCL, but will the NCL regrid function do this for me, or is there another Python function or something else that I can use to do this?
Thanks!
