Climate change impacts all of us in various ways. Changes in soil moisture have a pronounced effect on agricultural production, which in turn impacts the food we grow to eat, and changes in precipitation patterns are leading to increases in drought in certain regions and causing flooding in others. All of which are influenced by interactions among components of Earth involving the atmosphere, ocean, land, ice, and life. These factors combine with long-term changes forced largely by human activities, such as the release of greenhouse gases, drive the climate system and result in distinct
IMERG Rainfall Totals from Cyclone Tauktae
NASA combined data from multiple satellites in the GPM Constellation to estimate precipitation rates and totals from Tropical Cyclone Tauktae in May 2021. The below animation shows precipitation rates (blue/yellow shading) and accumulations (green shading) at half-hourly intervals from May 12-19, 2021, derived from NASA's IMERG algorithm. Underneath the precipitation data, cloud cover is shown in shades of white/gray based on geosynchronous satellite infrared observations. On top of the precipitation data, the cyclone's approximate track is displayed based on estimates from the Joint Typhoon
