P3.14 QUANTIFICATION OF A DRY BIAS IN RADIOSONDE HUMIDITY PROFILES OVER ANTARCTICA: IMPLICATIONS FOR CALCULATIONS OF OUTGOING LONGWAVE RADIATION

Middle to upper tropospheric humidity plays a large role in determining outgoing longwave radiation. Tropospheric humidity is routinely measured by ra-diosondes, even though radiosonde humidity measure-ments typically become increasingly inaccurate with height. Among the problems experienced by the...

Description
Summary:Middle to upper tropospheric humidity plays a large role in determining outgoing longwave radiation. Tropospheric humidity is routinely measured by ra-diosondes, even though radiosonde humidity measure-ments typically become increasingly inaccurate with height. Among the problems experienced by the hu-midity sensor is a dry bias caused by illumination with solar radiation. During the austral summer of
