During debugging of ufs-community/ufs-weather-model#2562 it was found that the source 1/4deg ice files can contain phantom ice. This is where there is no ice coverage sum(aicen(ncat))==0 but there is ice volume max(vicen(ncat)>0) as shown below

A second issue was found where sum(aicen(ncat))>0 on land as shown here

The downscaling utility should be updated to check for these two pathologies.
