OBSERVATION SPACE STATISTICS
Altimetry
- Absolute dynamic topography (ADT) observations from NESDIS RADS
- XGM2016 geoid
- Satellites: CryoSat-2, Jason-3, SARAL, Sentinel-3A/3B
NOTE: These observations are currently in a monitoring mode, they do not yet impact the analysis. Full use of these observations will be added in a later code change.
Time Averaged Statistics
Time averaged statistics for up to the past 30 days. Stats are binned on a 1 degree grid.
Counts
Number of observations passing quality control (left) and the percentage of bad obs removed (right).
RMSD
Root mean squared deviation for O-B (left) and O-A (right).
Bias
Bias for O-B (left) and O-A (right).
Timeseries Statistics
Timeseries of bias and RMSD for O-B (solid line) and O-A (dashed line).
If multiple colors are shown, they represent the realtime/retrospective runs from the given
git hash of the release/nightly or master branches of the repository.
