CHG Station Climatology Database (CSCD)The Climate Hazards group InfraRed Precipitation (CHIRP) with Stations (CHIRPS): Development and Validation Pete Peterson1, Chris C Funk 2,1, Gregory J Husak1, Diego H Pedreros2, Martin Landsfeld1, James P Verdin2 and Shraddhanand Shukla1 1 Geography, University of California, Santa Barbara, CA, United States US Geological Survey American Geophysical Union Fall Meeting, , San Francisco, CA, USA chg.geog.ucsb.edu Validation - How good is CHIRPS? GPCC 2.5o, CHIRPS 0.05o GPCC ends in 2012, CHIRPS topped off in near-real time Overview Estimating precipitation variations in space and time is an important aspect of drought early warning and environmental monitoring. An evolving drier-than-normal season must be placed in historical context so that the severity of rainfall deficits may quickly be evaluated. To this end, scientists at the U.S. Geological Survey Earth Resources Observation and Science Center, working closely with collaborators at the University of California, Santa Barbara Climate Hazard Group (CHG), have developed a quasi-global (50oS-50oN, 180oE-180o W), 0.05o resolution, 1981 to near-present gridded precipitation time series: the Climate Hazard group InfraRed Precipitation with Station (CHIRPS) data archive. The primary time step is the pentad which is used to create 6-hourly, daily, dekad, monthly and 3-monthly precipitation products. Quick preliminary pentad and daily CHIRPS are available every pentad on the 2nd day of the following pentad. Final products for all time steps are produced after the 15th of the following month to allow for the acquisition of all available station data. Trends Independent stations CHIRP B1 IR coverage CHPclim is the CHG Precipitation gridded 0.05o monthly climatology derived from station data. Regress Cold Cloud Duration (CCD) to TRMM-V7 pentad precipitation at each pixel, for each month ( ) and use to calculate near real time precipitation (IRP) from CPC-IR (½ hourly). Apply to B1 IR data (3-hourly) from to extend IRP time series. CHIRPS = CHIRP + Blended Stations Citations Funk, C., J. Michaelsen, and M.
