Correlation Between Grace Terrestrial Water Storage Anomaly and TRMM Precipitation

The change of water resources under global warming is one of the most important issues faced by national economy and social development. Accurate estimation and analysis of Terrestrial Water Storage Anomaly (TWSA) are important for understanding global and regional water cycle process. Gravity Recovery and Climate Experiment (GRACE) satellite data is used to inverse water storage change in China and the correlation between it and precipitation from Tropical Rainfall Measuring Mission (TRMM) is also analyzed. The study shows that GRACE TWSA and TRMM precipitation are consistent and linear. In the best regression model, R2 and RMSE are 0.8025 and 11.1469 respectively, which suggests that precipitation is the source of water supply and also the main impact of water storage change.
