The ROHP (Radio-Occultation and Heavy Precipitation) experiment aboard the Spanish Earth-observation satellite PAZ is designed to test a new technique of surveying the atmosphere. It will provide coincident thermodynamic and precipitation information with high vertical resolution within regions with thick clouds. Currently there isn’t any instrument able to offer this set of observations simultaneously. This might help understanding the thermodynamic conditions underlying intense precipitation, which is relevant because these events remain poorly predicted with the current climate and weather model parameterization.
ROHP-PAZ is the work of an IEEC team of the Institute of Space Sciences (ICE, CSIC) who has created the new measurement concept, has found international funding and partners, has designed the experiment and will be responsible of its execution.
