The Radio Occultation (RO) instrument is a passive instrument measuring the time variation of the excess path length of Global Navigation Satellite System (GNSS) signals as they are occulted by the atmosphere.
The JEDI UFO system has multiple observation operators with differing implementations that can be compared on the same observation data. Additionally satellites can be grouped by mission for comparison across operators.
The source for the GNSSRO data is the NCEP NOMADS system GDAS BUFR data converted to IODA format by the IODA-converters.
For each variable and/or satellite channel, shown are the observation counts (left), O-B RMSD (center), and O-B bias (right).
