The campaign utilized many data collection technologies, some of which are relatively new. In this study, we used saildrone uncrewed surface vehicles, one of the newer cutting edge technologies available for marine data collection, to validate Level 2 and Level 3 Soil Moisture Active Passive (SMAP) satellite and Hybrid Coordinate Ocean Model (HYCOM) sea surface salinity (SSS) products in the Western Tropical Atlantic. The saildrones observed fine-scale salinity variability not present in the lower-spatial resolution satellite and model products. In regions that lacked significant small-scale salinity variability, the satellite and model salinities performed well. However, SMAP Remote Sensing Systems (RSS) 70 km generally outperformed its counterparts outside of areas with submesoscale SSS variation, whereas RSS 40 km performed better within freshening events such as a fresh tongue. HYCOM failed to detect the fresh tongue. These results will allow researchers to make informed decisions regarding the most ideal product and its drawbacks for their applications in this region and aid in the improvement of mesoscale and submesoscale SSS products, which can lead to the refinement of numerical weather prediction (NWP) and climate models.<\/jats:p>","DOI":"10.3390\/rs14143375","type":"journal-article","created":{"date-parts":[[2022,7,14]],"date-time":"2022-07-14T00:12:40Z","timestamp":1657757560000},"page":"3375","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Validating Salinity from SMAP and HYCOM Data with Saildrone Data during EUREC4A-OA\/ATOMIC"],"prefix":"10.3390","volume":"14","author":[{"given":"Kashawn","family":"Hall","sequence":"first","affiliation":[{"name":"Caribbean Institute for Meteorology and Hydrology, Husbands, St. James BB23006, Barbados"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7458-2838","authenticated-orcid":false,"given":"Alton","family":"Daley","sequence":"additional","affiliation":[{"name":"Caribbean Institute for Meteorology and Hydrology, Husbands, St. James BB23006, Barbados"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0722-4256","authenticated-orcid":false,"given":"Shanice","family":"Whitehall","sequence":"additional","affiliation":[{"name":"Caribbean Institute for Meteorology and Hydrology, Husbands, St. James BB23006, Barbados"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2672-312X","authenticated-orcid":false,"given":"Sanola","family":"Sandiford","sequence":"additional","affiliation":[{"name":"Caribbean Institute for Meteorology and Hydrology, Husbands, St. James BB23006, Barbados"}]},{"given":"Chelle L.","family":"Gentemann","sequence":"additional","affiliation":[{"name":"Farallon Institute, Petaluma, CA 94952, USA"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"206","DOI":"10.3389\/fmars.2019.00206","article-title":"The Tropical Atlantic Observing System","volume":"6","author":"Foltz","year":"2019","journal-title":"Front.
