Since 2010, WRA has been actively using TRMM data for water resource and flood defence projects, particularly in areas of sparse data. David Plinston
is leading this initiative and our TRMM data service provides continuous rainfall time-series and rainfall intensity-duration-frequency [IDF] curves for any point on the globe between the 50 degree latitudes, in formats which are easy to use for hydrological analysis.
WRA’s IDF software analyses TRMM rainfall by quarter degree grid cell for any duration between 3 and 72 hours for the post-1998 period, a record of 192 months of short-duration rainfall data.
The data have been used, tested and validated by WRA in Africa, the Middle East and Far East, by comparison of statistics with ground stations.
WRA provides processed rainfall and IDF data as a commercial service for clients, and the pricing is based on the number of quarter degree grid cells per grid cell and number of IDF curves and tables provided.
