As part of generating a gridded climate data product, Ben Ho (UCAR/COSMIC program) has found a list of occultations which compare poorly to ECMWF reanalysis. These profiles may have problems due to bad L2 tracking or owing to localized ionospheric irregularities that were not detected in the normal CDAAC quality checking against climatology. Please make a note of these problematic occultations when using these data in climate studies.
