IPWG U.S. Validation Page



* This validation is performed against daily rain gauge analyses and include various precipiation estimates that incorporate
precipitation from multiple satellites. However, the MiRS and MSPPS estimates are derived from a single satellite and thus
are at a serious disadvantage, from a sampling perspective, compared to the multi-satellite estimates.

Histograms of Precipitation Rates                  
NOTES:

(1) Because the rain gauge data are objectively analyzed, very light precipitation rates (< 0.1 mm/day)
are spread out spatially and are not real, therefore the histograms begin at 0.1 mm/day.

(2) The message "entire grid undefined" on the plots before the JJA 2008 season reflects the fact that
MSPPS & MiRS data were not collected until after that season.
