Description
Summary:Solar and terrestrial radiation measurements that were obtained at Amundsen-Scot>t (South Pole) Station and on Ice lsland (Bravo) T-3 are presented for representative summer and winter months. Of the South Polar net radiation loss during April 1958, approximately 20 percent of the energy came from the snow and 80 percent from the air. The actual atmospheric cooling rate during that period was only about lj6 of the suggested radiative cooling rate. The annual net radiation at various places in Antarctica is presented. During 1058, the South Polar atmosphere transmitted about 73 percent of the annual extraterrestrial radiation, while at T-3 the Arctic atmosphere transmitted about 56 percent. The albedo of melting sea ice is discussed. Measurements on T-3 during July 1958 indicate that the net radiation is positive on both clear and overcast days but greatest on overcast days. Refreezing of the surface with clear skies, as observed by Untersteiner and Badglep, is discussed. 1. INTRODUCTION Ocean. This Island was about 11 miles 5 by in size and The elliptical orbit of the earth brings it about 3 million about 52 meters thick (Crary et al. [2]) in 1953 when it miles farther from the sun at aphelion than at perihelion; drifted near 88 ' N., looo W. In the years that followed
