  History:
Wed Oct 22 11:45:57 2025: ncatted -a units,permafrost_extent,c,c,1 /home/nate/.cache/ilamb3/0.1/permafrost/Obu2018/Obu2018.nc Downloaded on 2023-07-31 and generated netCDF file on 2023-08-15 with https://github.com/rubisco-sfa/ILAMB-Data/blob/master/permafrost/Obu2018/convert.py. We have imposed a glaciated area mask in particular to remove much of Greenland where some models report soil temperatures.
