Notes on POP2 Tripolar grids scrip file fix: With the introduction of NUOPC caps, an issue was discovered in POP2 tripolar SCRIP grid files and, consequently, the corresponding ESMF mesh files. It appears that the tripolar SCRIP file latitudes are different than the internal POP/CICE coordinates at the first row (i.e., southermost row). To fix that, we set the center and corner latitutes of the first row in SCRIP file to be the same as the internal POP2 coordinates (obtained from POP2 history files.) This is done by the scripts in this directory
