Non-tidal atmospheric angular momentum
Website under construction
Here we provide all auxiliary atmospheric angular momentum data produced for the construction of physical-consistent geodetic residuals GAHS.
GAHS are calculated as residual of the geodetically observed angular momentum
GAHS = GAM-(AAM+HAM+SLAM). Under the assumption that the sum of model-based AAM, OAM, HAM, and SLAM can be compared to GAM, GAHS provides an estimate of ocean angular momentum independend of ocean models.
