Hurricane Ida IMERG Totals
All eyes were on Hurricane Ida as it made landfall in Louisiana on Aug. 29, 2021, but many people were taken by surprise by the power of Hurricane Ida's remnants when they reached Virginia during the day on Sept.1 and New York City late at night on Sept. 1 into early morning on Sept. 2. The below animation shows the precipitation that fell during the entire lifecycle of Ida from before landfall in Louisiana through the impacts on New York City.

NASA/JAXA GPM Satellite Eyes Hurricane Ida Shortly Before Landfall
Hurricane Ida struck southeast Louisiana as a powerful Category 4 storm on Sunday, Aug. 29, 2021 - the 16th anniversary of Hurricane Katrina’s landfall in 2005. Ida brought destructive storm surge, high winds, and heavy rainfall to the region, and left over 1 million homes and businesses without power, including the entire city of New Orleans. The NASA / JAXA GPM Core Observatory satellite flew over the eye of Ida shortly before landfall at 10:13 a.m. CDT (1513 UTC), capturing data on the structure and intensity of precipitation within the storm. This animation shows NASA's IMERG multi
GPM DPR overflight of Hurricane Henri 22 Aug 2021
In the North Atlantic, the tropical system known as Henri reached hurricane status on Saturday, August 21, 2021. At the time, it was approaching a landfall in New England. Between Friday and Sunday, Henri was observed three times by the Dual-frequency Precipitation Radar (DPR) on the core satellite of NASA's Global Precipitation Measurement (GPM) mission. The GPM satellite's first two flyovers of Henri occurred just 10 hours apart and revealed a remarkably unchanging structure that was being impacted by wind shear. A third overflight occurred a day later, when wind shear had abated and Henri
GPM Overpass of Tropical Cyclone Fred on August 16, 2021.
Tropical Storm Fred, the 6th named storm of the 2021 Atlantic hurricane season, began as a westward moving disturbance in the central Atlantic east of the Lesser Antilles. The system passed through the southern Leeward Islands during the early morning hours of August 10 but still lacked a well-defined center of circulation. Despite significant thunderstorm activity within the system, it wasn’t until late that evening, when the system was passing just south of Puerto Rico, that the National Hurricane Center (NHC) identified a well-defined circulation and upgraded the system to Tropical Storm
IMERG precipitation over China for July 17 to 28, 2021
During July 17 to 28, 2021, several storm systems brought heavy rain to parts of China and surrounding countries, while a nine-month-long drought persists in an adjacent part of China. NASA's multi-satellite precipitation algorithm has been monitoring this rainfall in near real-time, and the estimates are distributed to weather-forecasting agencies and disaster-monitoring organizations. This algorithm is called IMERG, the Integrated Multi-satellitE Retrievals for GPM. GPM is the NASA / JAXA Global Precipitation Measurement mission, which launched its Core Observatory satellite in 2014. Two
