Summary[edit]

Description
English: Late on November 14, 2017, a slow-moving weather system in the Mediterranean brought torrential rain and flash floods to Greece. Among the hardest hit places was Mandra, a town west of Athens. Floods there left hundreds of people homeless and claimed several lives.

This three-dimensional map shows satellite-based measurements of the rain that fell in the area from November 14 to 16. The data come from the Integrated Multi-Satellite Retrievals for GPM (IMERG), a product of the Global Precipitation Measurement mission. The precipitation data was draped over terrain data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER).

The GPM satellite is the core of a rainfall observatory that includes measurements from NASA, the Japan Aerospace Exploration Agency, and five other national and international partners. These rainfall totals are regional, remotely-sensed estimates, and local amounts can be significantly higher when measured from the ground.
Deutsch: spät am 14. November 2017 brachte ein sich langsam bewegendes Wettersystem im Mittelmeer Starkregen und Sturzfluten nach Griechenland. Unter den am stärksten betroffenen orten war Mandra, eine Stadt westlich von Athen. Durch die Überschwemmmungen wurden hunderte von Bewohnern obdachlos undmehrere Personen kamen um.

Diese dreidimensionale Kartendarstellung zeigt satellitenbasierende Messungen des gefallenen Regens in der Region vom 14. bis 16. November. Diese Daten sind Integrated Multi-Satellite Retrievals for GPM (IMERG), ein Produkt der Mission Global Precipitation Measurement. Die Niederschlagsaten wurden über Landschaftsdaten gelegt, die mit dem Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) ermittelt wurden.

Der GPM-Satellit ist das Kernstück der Niederschlagsbeobachtungen, die auf Messungen durch die NASA, die Japan Aerospace Exploration Agency und fünf weitere nationale und internationale Partner basieren. Diese Niederschlagsmengen sind regionale, durch Fernbeobachtung ermittelte Schätzwerte, die bei Messungen vor Ort signifikant höher ausfallen können.
