The SALVAL tool integrates long-term satellite products, global in situ datasets, and community-agreed-upon validation protocols into an online and interactive platform. The SALVAL tool, available on the ESA Cal\/Val portal, was developed by EOLAB under the framework outlined by the Committee on Earth Observation Satellites (CEOS) Working Group on Calibration and Validation (WGCV) Land Product Validation (LPV) subgroup, and provides transparency, consistency, and traceability to the validation process. In this demonstration, three satellite-based albedo climate data records from different operational services were validated and intercompared using the SALVAL platform: (1) the Climate Change Service (C3S) multi-sensor product, (2) the NASA MODIS MCD43A3 product (C6.1) and (3) Beijing Normal University\u2019s Global LAnd Surface Satellites (GLASS) version 4 products. This work demonstrates that the three satellite albedo datasets enable long-term reliable and consistent retrievals at the global scale, with some discrepancies between them associated with the retrieval processing chain. The three satellite albedo products show similar uncertainties (RMSD = 0.03) when comparing the best quality retrievals with ground measurements. The SALVAL platform has proven to be a useful tool to validate and intercompare albedo datasets, allowing them to reach stage 4 of the CEOS LPV validation hierarchy.<\/jats:p>","DOI":"10.3390\/rs15041081","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T04:51:46Z","timestamp":1676523106000},"page":"1081","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Surface ALbedo VALidation (SALVAL) Platform: Towards CEOS LPV Validation Stage 4\u2014Application to Three Global Albedo Climate Data Records"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9028-9925","authenticated-orcid":false,"given":"Jorge","family":"S\u00e1nchez-Zapero","sequence":"first","affiliation":[{"name":"Earth Observation Laboratory (EOLAB), C\/ Savina 8\u2013A4, 46980 Paterna, Val\u00e8ncia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrique","family":"Mart\u00ednez-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Earth Observation Laboratory (EOLAB), C\/ Savina 8\u2013A4, 46980 Paterna, Val\u00e8ncia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Camacho","sequence":"additional","affiliation":[{"name":"Earth Observation Laboratory (EOLAB), C\/ Savina 8\u2013A4, 46980 Paterna, Val\u00e8ncia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuosen","family":"Wang","sequence":"additional","affiliation":[{"name":"Earth System Science Interdisciplinary Center, University of Maryland College Park, College Park, MD 20742, USA"},{"name":"Terrestrial Information Systems Laboratory, NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominique","family":"Carrer","sequence":"additional","affiliation":[{"name":"CNRM\u2013\u2013Centre National de Recherches M\u00e9t\u00e9orologiques (CNRM), Universit\u00e9 de Toulouse, M\u00e9t\u00e9o France, CNRS, 42 Avenue Gaspard Coriolis, 31057 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Crystal","family":"Schaaf","sequence":"additional","affiliation":[{"name":"School for the Environment, University of Massachusetts Boston, Boston, MA 02125, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5888-0061","authenticated-orcid":false,"given":"Francisco Javier","family":"Garc\u00eda-Haro","sequence":"additional","affiliation":[{"name":"Earth Physics and Thermodynamics Department, Faculty of Physics, Universitat de Val\u00e8ncia, Dr. Moliner, 46100 Burjassot, Val\u00e8ncia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaime","family":"Nickeson","sequence":"additional","affiliation":[{"name":"Science Systems and Applications, Inc., 10210 Greenbelt Rd., Lanham, MD 20706, USA"},{"name":"NASA Goddard Space Flight Center (GSFC), Biospheric Sciences Laboratory, 8800 Greenbelt Rd., Greenbelt, MD 20771, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4776-1918","authenticated-orcid":false,"given":"Michael","family":"Cosh","sequence":"additional","affiliation":[{"name":"USDA Agricultural Research Service, Hydrology and Remote Sensing Laboratory, 10300 Baltimore Ave., Beltsville, MD 20705, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1016\/0034-4257(94)00062-R","article-title":"Land processes in climate models","volume":"51","author":"Dickinson","year":"1995","journal-title":"Remote Sens.
