Widespread flooding has recently affected South America and Paraguay has been especially hard hit. A NASA analysis showed locations in central and southern Paraguay that received the largest rainfall totals from 23 to 29 December.

In Paraguay, the Department of Meteorology and Hydrology (DMH) and the Emergencies Office have attributed this late-summer flooding to this year's strong El NiƱo phenomenon.

"Particularly punishing are the heavy rains that have caused serious flooding across South America," said climatologist Bill Patzert, of NASA's Jet Propulsion Laboratory, Pasadena, California.

According to the Paraguay DMH, rainfall over central and south central parts of Paraguay showed rainfall totals up to 400 mm (15.75 inches) from the period of 1 through 23 December.

The NASA analysis of rainfall was generated using the Integrated Multi-satellitE Retrievals for GPM (IMERG) data product. IMERG rainfall estimates are computed in near-realtime. Global precipitation estimates are provided by IMERG through the use of data from satellites in the Global Precipitation Measurement (GPM) and is calibrated with measurements from the GPM Core Observatory as well as rain gauge networks around the world.
