This visualization shows the correlation and lag time of surface soil moisture following precipitation events over Australia, India, and the United States. It uses the new NASA-USDA-FAS Soil Moisture product, a joint effort of NASA and the USDA Foreign Agricultural Service, and the global Integrated Multi-satellitE Retrievals for GPM (IMERG) precipitation dataset, which provides rainfall rates for the entire world every thirty minutes. This animation shows the 30-minute rainfall product, while the soil moisture data is a three-day moving average. Anomaly data is expressed as a standardized anomaly, e.g. (value-average)/stdev, and as such is unitless.

Datasets used in this visualization

NASA-USDA-FAS Soil Moisture (A.K.A. Surface Soil Moisture corrected with SMOS imagery and assimilated by the Ensemble Kalman Filter)
Data Compilation | NASA and USDA

The surface soil moisture product is corrected by integrating satellite-derived Soil Moisture Ocean Salinity (SMOS) mission surface soil moisture retrievals into the modified Palmer two-layer soil moisture model. The SMOS imagery helps to correct the modified Pal
