NASA's IMERG measures flooding rainfall in Peru
03 March 2016
Heavy rainfall recently caused flooding, landslides and power outages in some areas of Peru. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) measured that rainfall by using a merged precipitation product from a constellation of satellites.
GPM is the Global Precipitation Measurement mission, which is a satellite co-managed by NASA and the Japan Aerospace Exploration Agency and is used in NASA's IMERG data. GPM provides next-generation observations of rain and snow worldwide every three hours.
Extremely heavy rainfall was reported in northern Peru on 26 February and 27 February 2016. Thousands were made homeless and at least two people were reportedly killed from the severe weather. The strong El Niño was partially blamed for the abnormally high rainfall in that area.
NASA's IMERG data collected from 23-29 February 2016 were used to estimate rainfall totals over this area of South America. The highest rainfall total estimates for this period were over 700 mm (27.6 inches). These extreme rainfall total estimates were shown east of the Andes in southeastern Peru and Bolivia.
