Distribution of contributing observations (Fig. 1 of Rigor et al. 2000). Observations from many land stations, several manned
Arctic stations, and numerous Argo floats are blended in this data
set. The predominance of Greenland observations are along the coasts.

differences in excess of 5C mostly near the coastlines.

netCDF format. I interpolated the data onto a 1-degree
latitude-longitude using Cressman interpolation of the 5 closest grid
points. The e-folding distance of the weights is 1-degree (out of
360). This interpolation is fast and dirty, and is not intended to be
the definitive equal-angle representation of this data set.
