Rainfall Estimate for the United States

Rainfall estimates for 1-hour, 2-hour and storm totals, and is updated on the same schedule as Doppler radar.  CustomWeather has developed a breakthrough system that utilizes data supplied by NASA to estimate rainfall totals for both the past 3 hours and the past 24 hours.  Data is available on a 12-14 hour delay.  Rainfall estimates are made worldwide (between 50 degrees North and 50 degrees South) by analyzine a combination of actual grounds reports, infrared satellite imagery, and Doppler radar.  This cutting-edge system of satellite-based rainfall estimations enables CustomWeather to accurately estimate rainfall totals for the past 24 hours for any location worldwide.  Rainfall data is delivered daily for the previous day with information for both 3 hour totals and 24 hour totals.  Rainfall totals less than 2mm will not be reported as these amounts are frequently attributed to ground clutter.
