This approach uses spatiotemporal filtering techniques with optimized filters to be robust against the thermal noise and image reconstruction artifacts present in SMOS images. It is also possible to retrieve the Faraday rotation angle from the recovered VTEC maps in order to correct the effect that it causes in the SMOS brightness temperatures.<\/jats:p>","DOI":"10.3390\/rs12101604","type":"journal-article","created":{"date-parts":[[2020,5,18]],"date-time":"2020-05-18T11:34:14Z","timestamp":1589801654000},"page":"1604","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Deriving VTEC Maps from SMOS Radiometric Data"],"prefix":"10.3390","volume":"12","author":[{"given":"Roselena","family":"Rubino","sequence":"first","affiliation":[{"name":"CommSensLab Research Group, Polytechnic University of Catalonia, c\/Jordi Girona 1-3, 08034 Barcelona, Spain"}]},{"given":"Nuria","family":"Duffo","sequence":"additional","affiliation":[{"name":"CommSensLab Research Group, Polytechnic University of Catalonia, c\/Jordi Girona 1-3, 08034 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6380-3754","authenticated-orcid":false,"given":"Ver\u00f3nica","family":"Gonz\u00e1lez-Gambau","sequence":"additional","affiliation":[{"name":"Physical Oceanography Department, Institute of Marine Sciences, ICM-CSIC and Barcelona Expert Center, Pg.
