Precipitable Water Vapor Retrieval and Analysis by Multiple Data Sources: Ground-Based GNSS, Radio Occultation, Radiosonde, Microwave Satellite, and NWP Reanalysis Data

Figure 8

The six graphics show the retrieved PWV in global along the latitude by COSMIC radio occultation (a), FY3C radio occultation (d), ERA-Interim (c, f), and ERA5 (b, e) reanalysis data on February 4, 2016. (a, b, c) Retrieved PWV from COSMIC RO and interpolated total column water vapor from ECMWF ERA-Interim and ERA5 reanalysis data on COSMIC radio occultation sites. (d, e, f) Retrieved PWV from FY3C RO and interpolated total column water vapor from ECMWF ERA-Interim and ERA5 reanalysis data on FY3C radio occultation sites.
