A number of datasets are commonly used by the scientific community with climate analisis purposes: analysis generated by the major forecasting centers, and gridded datasets developed by different group of research. The objective of this work is to verify if the available gridded datasets of near surface temperature over southeast South America (SESA) give us confidence on detecting trends in daily extremes temperatures. Trends in maximum surface temperature (TX) and minimum surface temperature (TN) are estimated using the following datasets: NCEP-1, 20CR, ERA-40 and Tencer.
