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).

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).
