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.

NASA-USDA-FAS Soil Moisture (Surface Soil Moisture corrected with SMOS imagery and assimilated by the Ensemble Kalman Filter)
ID: 954The 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

NASA On Air: NASA's GPM Satellite Tracks Rain For Farmers Around The World (4/28/2016)
Read moreLEAD: A network of Earth-observing satellites is helping to track crop growing conditions around the world.1. Rainfall, shown here as radar-like moving bands of reds and yellows, can now be tracked every 30 minutes across most of the earth.2. The base maps of the continents change color indicating the available moisture (water) in the surface soils for growing crops. 3. This information is especially helpful to farmers waiting for the summer monsoon rain in countries such as India that only have limited number of weather stations. TAG: The data is already being used by the USDA Foreign Agricultural Service. || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_1920x1080.00001_print.jpg (1024x576) [172.4 KB] || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_1920x1080.00001_searchweb.png (320x180) [91.0 KB] || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_1920x1080.00001_web.png (320x180) [91.0 KB] || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_1920x1080.00001_thm.png (80x40) [6.6 KB] || WSI_WEATHER_CHANNEL_NASAonAir-Soil_Moisture_1280x720.mov (1280x720) [1.2 GB] || WSI_WEATHER_CHANNEL_NASAonAir-Soil_Moisture_1920x1080.mov (1920x1080) [1.0 GB] || NBC_TODAY_NASAonAir-Soil_Moisture_NBC_Today.mov (1920x1080) [100.6 MB] || Weather_Central_NASAonAir-Soil_Moisture_Weather_Central.wmv (1280x720) [10.1 MB] || Accuweather_NASAonAir-Soil_Moisture_Accuweather.avi (1280x720) [10.4 MB] || BARON_SERVICE_NASAonAir-Soil_Moisture_baron.mp4 (1920x1080) [25.3 MB] || WC_PRORES_422_NASAonAir-Soil_Moisture_prores.mov (1920x1080) [509.3 MB] || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_960x540.m4v (960x540) [29.9 MB] || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_1280x720.m4v (1280x720) [55.5 MB] || IPAD_DELIVERABLES_NASAonAir-Soil_Moisture_iPad_1920x1080.m4v (1920x1080) [89.0 MB] || WEBM_NASAonAir-Soil_Moisture.webm (960x540) [13.9 MB] ||
