Abstract: Annual cycles of downwelling broadband infrared radiative flux and spectral downwelling infrared flux were determined using data collected at the South Pole during 2001. Clear-sky conditions are identified by comparing ...

Abstract: Estimates of cloud cover over the South Pole are presented from five different data sources: routine visual observations (1957?2004; Cvis), surface-based spectral infrared (IR) data (2001; CPAERI), surface-based broadband ...

Abstract: The response of radiosondes to an instantaneous change of environment was studied by taking the instruments from a warm building into the cold environment at South Pole Station. After being initialized inside, the radiosondes ...
