Stoke coefficients
We provide time-variable Stokes coefficients from various atmospheric,
oceanic and hydrological models. Products are available
here.
1. Operationnal products
- ATMIB: atmospheric loading estimated from surface pressure from ECMWF
operational model (3 hours), assuming an inverted barometer ocean
response to pressure forcing.
- ERA5_IB: atmospheric loading estimated from surface pressure from latest
ECMWF Reanalysis (ERA5) (1 hour), assuming an inverted barometer ocean
response to pressure forcing,
- ERA5_TUGO: atmospheric loading estimated from surface pressure
from latest ECMWF Reanalysis (ERA5) (1 hour), assuming a dynamic ocean
response to pressure & winds from TUGO-m barotropic model
(update of Carrere & Lyard, 2003),
- ERA5_hydro: hydrology loading (soil moisture and snow),
from ERA5 Reanalysis (0.25 degree, 1 hour).
- MERRA2: hydrology loading (soil moisture and snow), estimated from MERRA2
(Gelaro et al., 2017) (1 hour, 0.50x0.625 degree) model.
Permanently ice-covered regions have been masked out.
- GLDAS2: hydrology loading (soil moisture, snow and canopy water),
estimated from GLDAS/Noah v2.1 (Rodell et al., 2004)
(3 hours, 0.25 degree) model.
Permanently ice-covered regions (Greenland, Alaska, mountain
glaciers, etc.) have been masked out.
- ECCO2: non-tidal ocean loading estimated from ECCO2 (Menemenlis et al.,
2008) ocean bottom
pressure (daily, 0.25 degree).
2. Old products (no more updates)
- ATMMO: atmospheric loading estimated from surface pressure from ECMWF
operational model (3 hours), assuming a dynamic ocean response to
pressure & winds from TUGO-m barotropic model (Carrere &
Lyard, 2003) (3 hour & 0.25 degree).
- ERAin: atmospheric loading estimated from surface pressure from ERA interim
(ECMWF Reanalysis) model (6 hours), assuming an inverted barometer ocean
response to pressure forcing,
- ERAhyd: hydrology loading (soil-moisture and snow) estimated from ERA interim.
