NASA Calculates Matthew's Heavy Rains - Wide Shot

NASA satellite data was used to provide estimates of Hurricane Matthew's heavy precipitation over the course of seven days. NASA estimates were created from a combination of space-borne passive microwave sensors and showed very heavy rainfall amounts in Matthew's track and over Hispaniola. NASA's Integrated Multi-satellitE Retrievals for GPM or IMERG product is used to make estimates of precipitation from a combination of space-borne passive microwave sensors, including the GMI microwave sensor onboard the Global Precipitation Measurement mission or GPM satellite, and geostationary IR (infrared) data. This data visualization shows IMERG rainfall estimates for the period from Sept. 29 to Oct. 5, 2016 for the northeastern Caribbean in association with the passage of Hurricane Matthew indicated by storm symbols. Beginning at 00 UTC on the Sept. 30 rainfall totals associated with Matthew are in excess of 10 inches all along its track, reaching upwards of 25 inches when the storm was intensifying on the Sept. 30. Over land, IMERGE shows wide areas of between 15 to 20 inches of rain all along the southern coasts of Haiti and the Dominican Republic on the island of Hispaniola. Rainfall am
