Abstract
The aim of this study is to propose an easy way to use the Reanalysis data, applying statistical downscaling, to estimate air temperature, relative humidity and precipitation in regions with a lack or shortage of meteorological data. The study region was the southwest of Buenos Aires province, Argentina. Statistical techniques were applied to in situ and Reanalysis (NCEP/NCAR) numerical model data. In short periods (10 years), the best fits were observed in the air temperature, especially in autumn and spring, while relative humidity and precipitation presented some differences. However, in long periods (30 years) the estimated data is useful for climatic studies due to its good fit between in situ and Reanalysis model data.
