| Three precipitation products with global coverage have been analyzed for the ecuadorian coastal zone (below 1000 m above sea level), during the period 1964-1994, to evaluate their behavior and consistency, in addition to their response to the governing seasonal cycle. The precipitation products are : CRU (Climate Research Unit, University of East Anglia), GPCC (Global Precipitation Climatology Centre, Deutscher Wetterdients), and UDEL (University of Delaware), regridded at a regular grid of 0.25°. The reference dataset chosen (INMAHI 12k) is based on observations from 51 rain-gauges located at meteorological stations on the Ecuadorian littoral, gridded at 0.25°. The analysis is based, principally, on comparison of the products with the observed annual... |
