OBSERVATION SPACE STATISTICS
Sea Surface Temperature
- Sea surface temperature retrievals from the Advanced Clear Sky Processor for Ocean (ACSPO)
- Sensors: AVHRR_FRAC
- Satellites: Metop-C
- (Currently only using a single AVHRR satellite, future plans will expand to all current AVHRR and VIIRS satellites)
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.
Global
