IABP-POLES 2-Meter Air Temperature Data SetEntry ID: IABP_POLES_2meter
Abstract: The POLES Arctic Gridded 2-meter Air Temperature Data Set provides
optimally interpolated 2-meter air temperatures on the EASE (Equal
Area SSM/I Earth) grid at intervals of 4 times daily for the years
1979 through 1992. Munoz and Martin (1995) give a full description
of the optimal interpolation scheme.
The EASE grid used for this data set is a subset of the rectangular
grid currently being used ... as a standard by the POLES group and is described
in Schweiger and Francis (1995). Each of the grid points is separated
by 200.54 km. The geographic domain of the data set is that region
defined by the coastlines surrounding the seasonal and perennial ice
covered oceans and seas of the northern hemisphere.
The source of the temperature observations used in the scheme consist
of data from land stations, ship observations from the Comprehensive
Ocean-Atmosphere Data Set (COADS), Soviet North Pole (NP) drifting ice
stations, and Arctic drifting buoys. The temperature observations
were taken at 2-meter heights at the land, Soviet NP and marine
stations, and at heights varying from tens of centimeters to about 3
meters above the surface for the buoys. Because the ice on which the
buoys rest is thick, we make the assumption that the buoy temperatures
are also 2-meter air temperatures.
