CSR GRACE & GRACE-FO Dynamic Ocean Mascons RL06.2DO

RL06.2DO monthly mass anomaly grids from GRACE and GRACE-FO determined following CSR RL06.2 processing altered for Dynamic Ocean analysis.
GAD-based regularization constraints are used over the Arctic Ocean.
The mascon processing includes a specific handling of the major earthquakes in Japan and Andaman Bay, similar to what was done for the RL06.2EQ mascons (doi:10.18738/T8/ZE7DUD), with a model of the Earthquake signals removed from the mascons in those regions.
Additionally a GRD model is computed using the mascon ocean mask and consistent with Tamisiea et al., 2010, (doi:10.1029/2009JC005687) and removed from the mascons.
The Earthquake and GRD models are provided as a companion grids, but both signals are already corrected for in the RL06.2DO mascons.
All grids are provided globally with a quarter degree sampling in longitude/latitude. Only the ocean mascons are reported. The land mascons are set to "-99999.0". The grids cover the GRACE and GRACE-FO period from 04/2002 to 05/2024
