This paper reports on the validation of AERONET flux estimations at the TOA with the CERES (Clouds and the Earth\u2019s Radiant Energy System) instrument. The validation was made at eight AERONET sites worldwide with at least seven years of Level 2.0 and Version 3 data and representatives of mineral dust, biomass burning, background continental, and urban-industrial aerosol regimes. To co-locate in time and space the AERONET and CERES fluxes, several criteria based on time and distance differences and cloud coverage were defined. When the strictest criterion was applied to all sites, the linear relationship between the observed and estimated fluxes (y = 1.04x \u2013 3.67 Wm\u22122) was very close to the 1:1 ideal line. The correlation coefficient was 0.96 and nearly all points were contained in the \u00b115% region around the 1:1 line. The average flux difference was \u20132.52 Wm\u22122 (\u20130.84% in relative terms). AERONET overestimations were observed at two sites and were correlated with large aerosol optical depth (AOD) (&gt;0.2) Underestimations were observed at one desert site and were correlated with large surface albedos (&gt;0.2).<\/jats:p>","DOI":"10.3390\/rs11182168","type":"journal-article","created":{"date-parts":[[2019,9,18]],"date-time":"2019-09-18T11:01:15Z","timestamp":1568804475000},"page":"2168","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Validation of AERONET-Estimated Upward Broadband Solar Fluxes at the Top-Of-The-Atmosphere with CERES Measurements"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8287-9693","authenticated-orcid":false,"given":"Micha\u00ebl","family":"Sicard","sequence":"first","affiliation":[{"name":"CommSensLab, Dept. of Signal Theory and Communications, Universitat Polit\u00e8cnica de Catalunya (UPC), 08034 Barcelona, Spain"},{"name":"Ci\u00e8ncies i Tecnologies de l\u2019Espai-Centre de Recerca de l\u2019Aeron\u00e0utica i de l\u2019Espai\/Institut d\u2019Estudis Espacials de Catalunya (CTE-CRAE\/IEEC), Universitat Polit\u00e8cnica de Catalunya (UPC), 08034 Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/S0034-4257(98)00031-5","article-title":"AERONET\u2014A federated instrument network and data archive for aerosol characterization","volume":"66","author":"Holben","year":"1998","journal-title":"Remote Sens.
