The high temporal resolution of the Meteosat satellites and their long term availability since 1977 make their data highly valuable for climate studies. In order to ensure that the LSA SAF LST product continuously meets its target accuracy of 2 \u00b0C, it is validated with in-situ measurements from four dedicated LST validation stations. Three stations are located in highly homogenous areas in Africa (semiarid bush, desert, and Kalahari semi-desert) and typically provide thousands of monthly match-ups with LSA SAF LST, which are used to perform seasonally resolved validations. An uncertainty analysis performed for desert station Gobabeb yielded an estimate of total in-situ LST uncertainty of 0.8 \u00b1 0.12 \u00b0C. Ignoring rainy seasons, the results for the period 2009\u20132014 show that LSA SAF LST consistently meets its target accuracy: the highest mean root-mean-square error (RMSE) for LSA SAF LST over the African stations was 1.6 \u00b0C while mean absolute bias was 0.1 \u00b0C. Nighttime and daytime biases were up to 0.7 \u00b0C but had opposite signs: when evaluated together, these partially compensated each other.<\/jats:p>","DOI":"10.3390\/rs8050410","type":"journal-article","created":{"date-parts":[[2016,5,13]],"date-time":"2016-05-13T11:53:16Z","timestamp":1463140396000},"page":"410","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":125,"title":["Long Term Validation of Land Surface Temperature Retrieved from MSG\/SEVIRI with Continuous in-Situ Measurements in Africa"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5836-5430","authenticated-orcid":false,"given":"Frank-M.","family":"G\u00f6ttsche","sequence":"first","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Folke-S.","family":"Olesen","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8640-9170","authenticated-orcid":false,"given":"Isabel","family":"Trigo","sequence":"additional","affiliation":[{"name":"Instituto Portugu\u00eas do Mar e da Atmosfera (IPMA), Rua C ao Aeroporto, Lisboa 1749-077, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annika","family":"Bork-Unkelbach","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Martin","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,5,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2725","DOI":"10.1080\/01431161003743199","article-title":"The satellite application facility for land surface analysis","volume":"32","author":"Trigo","year":"2011","journal-title":"Int.
