             abstract = "Conventional and non-conventional atmospheric observations are of 
                         fundamental importance to allow reliable weather forecasts and 
                         allow researchers to improve the modeling of the atmosphere to 
                         create plausible scenarios for climate studies. However, 
                         conventional observations make up a very small number of 
                         observations available for use in weather forecasts and climate 
                         studies. Satellites, the non-conventional observations, observe 
                         the Earth System almost continuously in time and generate massive 
                         amounts of data that by far dominate the observation blend. Unlike 
                         conventional observing networks, satellites observe the Earth 
                         indirectly by measuring either emitted or absorbed radiation by 
                         the Earth and the instruments they carry, this makes their use 
                         somewhat harder than using conventional observations. Assessing 
                         how these various observing systems contribute to improving 
                         weather forecasts has become an essential tool to help scientists 
                         understand how to build future and better observing systems. The 
                         present study provides a comprehensive assessment of nearly 40 
                         years of observations used in the Reanalysis procedure, which 
                         essentially provides a mixture of model predictions and 
                         observations. This particular work examines the regional impact of 
                         observations on the Amazon basin during the period 1980 to 2017. 
                         On this relatively dense and difficult-to-access tropical forest 
                         region, certain observation systems have a particularly greater 
                         impact than they normally have when observed on a global scale, 
                         such as AMVs. The impact of the observations on short-range 
                         reanalysis forecasts has increased slightly over the course of the 
                         reanalysis. This increase is largely associated with an increase 
                         in available observations on this region.",
