Syed, T. H., Famiglietti, J. S., Rodell, M., Chen, J., and Wilson, C. R. (2008), Analysis of terrestrial water storage changes from GRACE and GLDAS, Water Resour. Res., 44, W02433, doi:10.1029/2006WR005779.
This paper seemed like one of early TWS studies using the GRACE observation. I felt it as a classical one, so decided to read through, focusing on figures and the conclusion.
Message: latitudinal dominant TWS component
|Dominant TWS pool||Dominant TWS flux|
|High latitudes||Snow water equivalent||Snowmelt-derived runoff|
|Mid latitudes||Soil moisture||Evaporation|
|Low latitudes||Soil moisture||Precipitation|
Their message can be summarized with this table.
All the figures below support this conclusion, except for the global map of major river basins.
Other messages include:
- Some major river basins dominate the global TWS variability
- Models w/o ground water and surface water processes showed a limitation in interpreting results due to the lack of information.
