Abstract
Altimeter observation on board an Earth-orbiting satellite (e.g., TOPEX) over sea surface is corrupted by, among others, the water vapor path delay. Such error can be calibrated for by a down-looking microwave radiometer. This article studies the effects of water vapor profile, sea surface temperature, wind speed and brightness temperature measurement error on the calibration precision. Proper frequency combinations are searched to minimize these effects.
