17th SSC Recomendation #6• The SSC recommends that a daily climatology data set
(gridded reanalysis) for the Amazon region should be organized by LBA specialists in the meteorology of South America, expressly for the purpose of input to land surface simulation models over the period starting in 2000 to the present (minus ca. 6 months). Required daily variables include mean, minimum and maximum air surface temperature, precipitation amount, mean solar radiation flux (downward shortwave), mean relative humidity, mean wind speed. The spatial resolution of the data set should be the highest possible under current observational and computational constraints.
