To an observer at the IGY Amundsen‐Scott South Pole Station, the polar plateau appears flat and unbroken as far as the eye can see in all directions. The sun is above the horizon continuously for six months, and the snow‐surface temperature remains below 0°C throughout the year. All of these factors make the geographic South Pole a most suitable place to measure the solar and terrestrial radiation fluxes, and associated energy exchanges, peculiar to a high‐altitude (9280 feet above, mean sea level), high‐latitude snowfield. The first such observations at the South Pole were made during the IGY. This report presents preliminary results of these
