This study compares VIIRS v1 LST with the ground in situ observations and with heritage LST product from MODIS Aqua and AATSR. Comparisons against U.S. SURFRAD ground observations indicate a similar accuracy among VIIRS, MODIS and AATSR LST, in which VIIRS LST presents an overall accuracy of \u22120.41 K and precision of 2.35 K. The result over arid regions in Africa suggests that VIIRS and MODIS underestimate the LST about 1.57 K and 2.97 K, respectively. The cross comparison indicates an overall close LST estimation between VIIRS and MODIS. In addition, a statistical method is used to quantify the VIIRS LST retrieval uncertainty taking into account the uncertainty from the surface type input. Some issues have been found as follows: (1) Cloud contamination, particularly the cloud detection error over a snow\/ice surface, shows significant impacts on LST validation; (2) Performance of the VIIRS LST algorithm is strongly dependent on a correct classification of the surface type; (3) The VIIRS LST quality can be degraded when significant brightness temperature difference between the two split window channels is observed; (4) Surface type dependent algorithm exhibits deficiency in correcting the large emissivity variations within a surface type.<\/jats:p>","DOI":"10.3390\/rs70912215","type":"journal-article","created":{"date-parts":[[2015,9,21]],"date-time":"2015-09-21T10:17:32Z","timestamp":1442830652000},"page":"12215-12241","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":69,"title":["Quality Assessment of S-NPP VIIRS Land Surface  Temperature Product"],"prefix":"10.3390","volume":"7","author":[{"given":"Yuling","family":"Liu","sequence":"first","affiliation":[{"name":"Earth System Science Interdisciplinary Center at University of Maryland, College Park, MD 20740, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunyue","family":"Yu","sequence":"additional","affiliation":[{"name":"Center for Satellite Applications and Research, NOAA\/NESDIS, College Park MD 20740, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Yu","sequence":"additional","affiliation":[{"name":"Earth System Science Interdisciplinary Center at University of Maryland, College Park, MD 20740, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5836-5430","authenticated-orcid":false,"given":"Frank","family":"G\u00f6ttsche","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology (KIT), Eggenstein-Leopoldshafen 76344, 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":"IPMA, Instituto Portugu\u00eas do Mar e da Atmosfera, Lisboa 1749-077, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,9,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"704","DOI":"10.1109\/TGRS.2011.2162338","article-title":"Validation of GOES-R satellite land surface temperature algorithm using SURFRAD ground measurements and statistical estimates of error properties","volume":"50","author":"Yu","year":"2012","journal-title":"IEEE Trans.
