Synergy product from combined ground based measurement of microwave radiometer, CLOUDNET synergy products and in situ radiosonde measurements. The specific CLOUDNET products used for the retrieval are the target categorization product and the cloud radar reflectivities corrected for gaseous and liquid attenuation. Essen radiosonde climatology provides prior information on temperature and absolute humidity. The cloud drop effective radius is an area weighted radius of the cloud drop particles.
Limitations: Retrieval is based on optimum estimation theory and must not be interpreted as an explicit solution, but as the most probable solution of a Gaussian distributed probability density function.
Provenance: Product is based on Cloudnet-processed remote-sensing data. IPT data provided by IGMK, University of Cologne
