Increased frequencies and intensities of heatwaves and droughts in the Amazon basin, highlight the urgent need to assess their coupled impacts on the region's energy and water fluxes, as well as vegetation stress. To address those challenges, we have first assessed the consistency representation of energy flux partitioning in widely used datasets (ERA5, ERA5-Land, GLDAS-2.1 &amp;amp; 2.2, FLDAS, GLEAM) over the Amazon basin through an indirect evaluation, leveraging satellite products, i.e. the amplitude of land surface temperature and the leaf area index. Our first analysis reveals spatial and temporal discrepancies among latent heat flux datasets covering the basin and identifies regions under water-limited conditions, particularly at the basin's borders and over eastern\/southeastern Amazonia. A second evaluation was made for extreme climatic events within the September-October-November of 2023 period, namely droughts and heatwaves as well as the interplay between both. Again, we consider reanalyses (now focusing ERA5) together with satellite LST and soil moisture products. By leveraging the latter, namely all-sky Land Surface Temperature (All-Sky-LST) derived from GOES satellite and soil moisture in the root zone provided by the Satellite Applications Facility on Support to Operational Hydrology and Water Management (H-SAF, H141\/H142) we could observe that prolonged droughts, combined with persistent heatwaves, may accelerate soil desiccation and disrupt evapotranspiration processes amplifying the region's climate vulnerabilities. This study underscores the suitability of satellite observations in assessing the representation of energy flux partitioning for widely used datasets, also applicable to climate models, offering pathways to improve the representation of key land surface processes and to develop more reliable predictions.<\/jats:p>","DOI":"10.5194\/egusphere-egu25-6209","type":"posted-content","created":{"date-parts":[[2025,3,14]],"date-time":"2025-03-14T19:28:01Z","timestamp":1741980481000},"source":"Crossref","is-referenced-by-count":0,"title":["Exploring the potential of remote sensing data to explain extreme events over the Amazon Basin."],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4027-8210","authenticated-orcid":false,"given":"Vitor","family":"Miranda","sequence":"first","affiliation":[]},{"given":"Juan Carlos","family":"Jim\u00e9nez","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8640-9170","authenticated-orcid":false,"given":"Isabel","family":"F.
