standard_name :: surface_temperature
long_name :: Surface Temperature of Sea Ice
comment :: When computing the time-mean here, the time-samples, weighted by the area of sea ice in the grid cell, are accumulated and then divided by the sum of the weights. Reported as ""missing"" in regions free of sea ice. Note this will be the surface snow temperature in regions where snow covers the sea ice.
units :: K
original_name :: COTSI/COAI
cell_methods :: time: mean (weighted by area of sea ice)

history :: 2011-06-13T20:53:57Z altered by CMOR: replaced missing value flag (-999) with standard missing value (1e+20). 2011-06-13T20:53:57Z altered by CMOR: Inverted axis: lat.
