Radiation observations on an ice floe on the Weddell Sea, 11/2004-01/2005
Listed in NASA Earthdata CMR
As a part of the international expedition Ice Station Polarstern (ISPOL), radiation measurements were carried out on ice floes on the Weddell Sea (68 degrees S, 55 degrees W) in 28.11.2004 - 2.1.2005.
Description
Two sets of radiation measurement equipment were used. Both sets measured downwelling and upwelling shortwave radiation and downwelling and upwelling longwave radiation.
One set was equipped with pyranometers and pyrgeometers manufactured by Kipp&Zonen, the other one with pyranometers and pyrgeometers by the Eppley Laboratory. The instruments were set up on two different locations on a single large ice floe. For a short period, one of them was also set up on a separate floe.

The data have been processed at the Finnish Institute of Marine Research (FIMR). The processed data set includes up- and downwelling components of short- and longwave fluxes (W/m2) with a resolution of one minute. The longwave components suffer from small dome heating effect, which has not been corrected.
Snow surface temperature and albedo were calculated from the radiation data. The temperatures suffer from the dome heating effect. For comparison, a corrected surface temperature was calculated from a weather mast air temperature and eddy flux measured sensible heat flux, using the Monin-Obukhov universal temperature profile.
The albedo is generally around 0.7 - 0.9, showing gradual decrease due to melting. There are some gaps of up to one day in the measurement series.
