The current L1 processor, version v620, was used for the second mission reprocessing in 2014. The new version, v724, is the one run in the third mission reprocessing and will become the new operational processor. The present paper explains the major changes applied and analyses the quality of the data with different metrics. The results have been obtained with numerous individual tests that have confirmed the benefits of the evolutions and an end-to-end processing campaign involving three years of data used to assess the improvements of the SMOS measurements quantitatively.<\/jats:p>","DOI":"10.3390\/rs12101645","type":"journal-article","created":{"date-parts":[[2020,5,21]],"date-time":"2020-05-21T11:31:18Z","timestamp":1590060678000},"page":"1645","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["SMOS Third Mission Reprocessing after 10 Years in Orbit"],"prefix":"10.3390","volume":"12","author":[{"given":"Roger","family":"Oliva","sequence":"first","affiliation":[{"name":"Zenithal Blue Technologies S.L.U., 08023 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7626-7033","authenticated-orcid":false,"given":"Manuel","family":"Mart\u00edn-Neira","sequence":"additional","affiliation":[{"name":"European Space Research and Technology Centre, European Space Agency, 2201 AZ Noordwijk, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5598-7955","authenticated-orcid":false,"given":"Ignasi","family":"Corbella","sequence":"additional","affiliation":[{"name":"Remote Sensing Laboratory, Universitat Politecnica de Catalunya, 08034 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josep","family":"Closa","sequence":"additional","affiliation":[{"name":"Airbus Defence and Space, Microwave Instruments department, 28692 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Albert","family":"Zurita","sequence":"additional","affiliation":[{"name":"Airbus Defence and Space, Microwave Instruments department, 28692 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fran\u00e7ois","family":"Cabot","sequence":"additional","affiliation":[{"name":"Centre D\u2019Etudes Spatiales de la Boisphere, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Khazaal","sequence":"additional","affiliation":[{"name":"Centre D\u2019Etudes Spatiales de la Boisphere, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Richaume","sequence":"additional","affiliation":[{"name":"Centre D\u2019Etudes Spatiales de la Boisphere, 31400 Toulouse, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juha","family":"Kainulainen","sequence":"additional","affiliation":[{"name":"Harp Technologies, 02150 Espoo, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Research and Development in Aerospace, 8006 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gon\u00e7alo","family":"Lopes","sequence":"additional","affiliation":[{"name":"Deimos Engenheria, 1998-023 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Tenerelli","sequence":"additional","affiliation":[{"name":"OceanDataLab, 29280 Locmaria Plouzan\u00e9, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raul","family":"D\u00edez-Garc\u00eda","sequence":"additional","affiliation":[{"name":"European Space Astronomy Centre, European Space Agency, 28692 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6380-3754","authenticated-orcid":false,"given":"Veronica","family":"Gonz\u00e1lez-Gambau","sequence":"additional","affiliation":[{"name":"Department of Physical Oceanography, Institute of Marine Sciences, CSIC and Barcelona Expertise Center, 08003 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raffaele","family":"Crapolicchio","sequence":"additional","affiliation":[{"name":"European Space Research Institute, European Space Agency, 00044 Frascati, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"666","DOI":"10.1109\/JPROC.2010.2043032","article-title":"The SMOS mission: New tool for monitoring key elements of the global water cycle","volume":"98","author":"Kerr","year":"2010","journal-title":"Proc.
