In addition to destructive winds measured at 81 mph (70 kts) a powerful winter storm called Desmond dropped record rainfall in northwest England over the past weekend. Desmond's unusually heavy rainfall resulted in wide spread damaging floods. Data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate rainfall for the period from November 30 to December 7, 2015. This analysis found that some rainfall near the Irish Sea measured over 392 mm (~15.4 inches) during this period. As much as 304 mm (~12 inches) of rain were reported to have fallen in only 24 hours

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
