The Sea and Land Surface Temperature Radiometer (SLSTR) was designed to provide measurements of the Earth\u2019s surface for operational and climate applications. In this paper the authors describe the traceability chain and derivation of uncertainty estimates for the thermal infrared channel radiometry. Starting from the instrument model, the contributing input quantities are identified to build up an uncertainty effects tree. The characterisation of each input effect is described, and uncertainty estimates provided which are used to derive the combined uncertainties as a function of scene temperature. The SLSTR Level-1 data products provide uncertainty estimates for fully random effects (noise) and systematic effects that can be mapped for each image pixel, examples of which are shown.<\/jats:p>","DOI":"10.3390\/rs13030374","type":"journal-article","created":{"date-parts":[[2021,1,25]],"date-time":"2021-01-25T09:59:40Z","timestamp":1611568780000},"page":"374","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Traceability of the Sentinel-3 SLSTR Level-1 Infrared Radiometric Processing"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9795-8781","authenticated-orcid":false,"given":"David","family":"Smith","sequence":"first","affiliation":[{"name":"RAL Space, Science and Technology Facilities Council, Harwell, Oxford OX11 0QX, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4176-9038","authenticated-orcid":false,"given":"Samuel E.","family":"Hunt","sequence":"additional","affiliation":[{"name":"National Physical Laboratory, Teddington TW11 0LW, UK"}]},{"given":"Mireya","family":"Etxaluze","sequence":"additional","affiliation":[{"name":"RAL Space, Science and Technology Facilities Council, Harwell, Oxford OX11 0QX, UK"}]},{"given":"Dan","family":"Peters","sequence":"additional","affiliation":[{"name":"RAL Space, Science and Technology Facilities Council, Harwell, Oxford OX11 0QX, UK"}]},{"given":"Tim","family":"Nightingale","sequence":"additional","affiliation":[{"name":"RAL Space, Science and Technology Facilities Council, Harwell, Oxford OX11 0QX, UK"}]},{"given":"Jonathan","family":"Mittaz","sequence":"additional","affiliation":[{"name":"Department of Meteorology, University of Reading, Reading RG6 6AL, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3517-1486","authenticated-orcid":false,"given":"Emma R.","family":"Woolliams","sequence":"additional","affiliation":[{"name":"National Physical Laboratory, Teddington TW11 0LW, UK"}]},{"given":"Edward","family":"Polehampton","sequence":"additional","affiliation":[{"name":"RAL Space, Science and Technology Facilities Council, Harwell, Oxford OX11 0QX, UK"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,22]]},"reference":[{"key":"ref_1","unstructured":"(2020, December 10).
