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).

Time Averaged Statistics (diff with master)

Time averaged statistics for up to the past 30 days. Stats are binned on a 1 degree grid, and shown as the difference from the master branch.

RMSD

Root mean squared deviation for O-B (left) and O-A (right), for master - release/nightly

Bias

Bias for O-B (left) and O-A (right), for master - release/nightly

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

NH

Northen hemisphere midlatitudes (20N-60N).

TP

Tropics (20S-20N).

SH

Southern hemisphere midlatitudes (20S-60S).
