Data from the Global Precipitation Measurement or GPM mission core satellite were used to help estimate rainfall data. GPM is a satellite co-managed by both NASA and the Japan Aerospace Exploration Agency. The city of Chennai on India's southeastern coast was hit particularly hard. More than 260 deaths have been reported in the Indian state of Tamil Nadu. Data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the flooding rainfall that fell from November 28 to Dec. 4, 2015. Over 400 mm (15.7 inches) of rainfall were estimated over areas south of Chennai

Extremely heavy rainfall over southeastern India caused deadly flooding in the middle of the month of November. Record setting rainfall has again caused deadly flooding in southern India. The latest deluge started at the end of November 2015 and generated flooding that has resulted in the reported deaths of 188 people. NASA's Integrated Multi-satellite Retrievals for GPM (IMERG) combines all data from 12 satellites into a continuously updated global map of rainfall at half hourly intervals. The rainfall accumulation analysis above was computed from data generated by IMERG during the period

Data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate the amount of rainfall that hurricane Sandra produced during the period from November 23-29, 2015. Sandra remained well off the Mexican coast during the most dangerous period from November 25-27, 2015 when Sandra was a powerful hurricane with sustained winds of up to 130 kts (150 mph). This analysis shows that much of Sandra's rainfall occurred over the open waters of the Eastern Pacific. This analysis indicates that moisture flowing from hurricane Sandra also caused heavy rainfall totals of over 700

The GPM core observatory satellite flew above hurricane Sandra on November 26, 2015 at 0706 UTC. Sandra had winds of 125 kts (144 mph) at that time making it a category three on the Saffir-Simpson hurricane wind scale. This means that Sandra is the latest major hurricane ever recorded in the eastern Pacific Ocean. Numerous powerful hurricanes were predicted in the eastern Pacific Ocean at the beginning of the hurricane season due to the development of the 2015 El Nino. Data captured by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments shows rain falling at a

Early this morning tropical Storm Sandra became the 18th named storm of the 2015 Eastern Pacific hurricane season. Intensifying tropical storm Sandra had winds of about 35 kts (40 mph) when the GPM core observatory satellite passed over on November 24, 2015 at 0719 UTC. A rainfall analysis derived using data collected at that time by from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments is shown. DPR discovered that the intense convective storms south of the tropical storm's center of circulation were dropping rain at a rate of over 80 mm (3.1 inches) per
