This display uses NASA/JAXA AMSR-E data (Ashcroft, P., and Wentz, F., 2006, updated daily, AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures V002, Boulder, Colorado USA, National Snow and Ice Data Center)
to estimate river discharge at over 2500 selected river measurement sites.
Please have patience…we are testing and calibrating the several thousand river measurement points in this display.  Tested (operational ) subsets for the U.S and for the Ganges Basin are currently in preparation.
Sites that are calibrated are all in the format shown on the Flood Observatory home page.  In many cases, non-calibrated sites include incorrect links and incorrect absolute discharge and runoff estimates.
