Microwave data for River Watch are from the Japanese Space Agency and NASA (AMSR-E, AMSR-2, TRMM, and GPM sensors). Data are initially processed by the Global Flood Detection and Alert System, GDACS, European Commission's Joint Research Center, Ispra, Italy. Optical flood mapping data are primarily from the two NASA MODIS sensors and, for current conditions, from the MODIS NRT processor at NASA Goddard Space Flight Center, USA. Due to cloud cover, optical mapping of flooding may lag behind River Watch/microwave sensor detection of flooding.
