Description
Many studies have by now demonstrated the accuracy of GNSS Radio Occultation (RO) data, and their usefulness as a stable climate reference. Because of this RO is now firmly established in climate reanalysis, where data are assimilated without bias correction. However, retrieval of water vapor data in the troposphere from RO refractivity requires a priori (background) information, which means that inhomogeneities in the background data may impact humidity Climate Data Records (CDRs).
Here, we will describe the ROM SAF CDRs and ICDR, with a focus on the temperature and humidity data records. The status and observed homogeneity of the RO time series is discussed, and the ROM SAF plans for development of the humidity CDRs are outlined.
