Introduction

The spatial and temporal distribution of precipitation over this region is needed for a variety of scientific uses such as climate diagnostic studies, and societal applications such as water management for agriculture and power, drought relief, flood control and flood forecasting. The task of quantifying the distribution is complicated by the fact that no single currently available estimate of precipitation has the necessary coverage and accuracy.

Under the sponsorship of La Plata Basin Regional Hydroclimate Project and with the endorsement of participating agencies, the CoSch (Combined Scheme) product is a new high-resolution, gauge-satellite-based analysis of daily precipitation over continental South America based on a combination of additive and multiplicative bias correction schemes to get the lowest bias when compared with the observed values (rain gauges). This technique appears to be a suitable tool to produce real-time, high-resolution, gauge-satellite-based analyses of daily precipitation over land in regional domains.

Daily validation results are for rain falling between 12 and 12 UTC on the specified day.
