TRMM and GPM Rain Gauge Data Archive

NASA, in support of first TRMM and now also GPM GV efforts has been collecting tipping bucket rain gauge data for over two decades. Early efforts used standalone tipping buckets with loggers that required manual downloads. In the GPM era, we are now able to use telemetered gauges using cell technology. The image to the left shows a dual-gauge platform that was designed by the University of Iowa. A similar system using updated computing technology is current being developed by NASA.
