Displacements for all sites

We provide 3-D (North, East & Up) displacements in millimeters for about 8500 sites worldwide (Figure 1) due to atmospheric, oceanic and hydrological surface loading processes in the Center-of-Mass (CM) & Center-of-Figure (CF) reference frames.

1. Operationnal products

New products: daily average of the time series are now available for the 1-hour & 3-hour products (e.g. ATMIB, all ERA5 & MERRA2 and GLDAS2).

Careful: As TUGO-m model is forced not only by atmospheric pressure but also by surface winds, loading estimates from classical ocean general circulation model (such as ECCO2) should not be added to the (ECMWF+TUGO-m) loading computations.

2. Old products (no more updates)

We use different land/sea mask models depending on the loading computations; for ECMWF products (operational or reanalysis), we use one with a 0.10-degree resolution, for the others (ECCO, GLORYS, GLDAS & MERRA), we use a 0.25-degree mask. Both of them are derived from the GMT (Generic Mapping Tools) database.
