The Atmosphere and Ocean non-tidal De-aliasing Level-1B (AOD1B) product is widely used in satellite gravimetry to correct for transient effects of atmosphere-ocean mass variability that would otherwise alias into monthly-mean global gravity fields. The most recent release is based on the global ERA5 reanalysis and ECMWF operational data together with simulations from the general ocean circulation model MPIOM consistently forced with fields of the same atmospheric data-set.

The talk focusses on the current status of the new release RL07. We present the changes made for RL07 with respect to the previous release RL06, the current status of the processing as well as the ongoing work in terms of consistency and uncertainty assessment.
