A new high-resolution precipitation estimation algorithm dubbed "PERSIANN-CCS'' (Precipitation Estimation form Remotely
Sensed Information using Artificial Neural Network--Cloud Classification System) at UC Irvine, with the goal to produce data
at spatio-temporal resolution (reaching 4km grid and 30-min) suitable for hydrological research and applications. The
PERSIANN-CCS estimates are validated with NWS WSR-88D Radar data and NOAA CPC gauge observations over US and Mexico
continent, respectively. The analyses are also compared with high quality gauge rainfall from Northwest Mexico North American
Monsoon Experiment (NAME) Event Raingage Network. In addition, the diurnal variability of rainfall from satellite, gauge,
and radar rainfall are cross-investigated. The extensive verification results show that PERSIANN-CCS is capable of providing
research quality precipitation analysis suitable for hydrometeorological modeling. Multi-year products, covering the region
of NAME (10°N-50°N and 135°W-65°W), are available back to March 1, 2000 and current updates are archived
routinely. Since September 2004, this operational system (http://hydis8.eng.uci.edu/CCS/) has been running in real-time and
the development of global version of this analysis is ongoing.
