Dear members, I am working on my paper with GPS radio occultation data (GPS RO) and looking for the comparative study of the GPS RO water vapour pressure with Radiosonde water vapour pressure. Hence I am trying to understand the COSMIC Data wet profiles of Wetprf and sonPrf (sonde profiles) by CDAAC.

Kindly help me on how the wetPrf and sonPrf profiles are related at the time of radio occultation Latitude, longitude and altitude receiving from the satellite? SonPrf is the radiosonde data which is co-located with the GPS RO data? Can I consider both wetprf and sonprf datasets from CDAAC for comparative studies? Or I should get Radiosonde data from other source and compare with GPS RO?
