In addition, to remove the uncertainty of the RVUS site itself, we used Landsat 8\/OLI as another benchmark with which to validate the accuracy and stability of VIIRS data through the RUVS site. The radiometric biases of the operational and reprocessed SNPP VIIRS bands were within \u00b14% and \u00b12%, respectively, as compared with the RUVS site and OLI, except for the M10 and M11 bands. In particular, the biases of the M5 and M7 bands were reduced by ~2% in this study. NOAA-20 VIIRS, on the other hand, was consistently lower than SNPP by ~2 to ~4% for all the bands. For the equivalent bands, the drift differences between operational and reprocessed SNPP\/VIIRS and OLI were no larger than 0.24%\/year and 0.1%\/year, respectively. The reprocessing algorithm of SNPP VIIRS efficiently improved the radiometric accuracy and stability of the SNPP\/VIIRS dataset to meet its specifications.<\/jats:p>","DOI":"10.3390\/rs14163913","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T23:44:03Z","timestamp":1660607043000},"page":"3913","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Evaluation of SNPP and NOAA-20 VIIRS Datasets Using RadCalNet and Landsat 8\/OLI Data"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3425-3968","authenticated-orcid":false,"given":"Xin","family":"Jing","sequence":"first","affiliation":[{"name":"Cooperative Institute for Satellite Earth System Studies (CISESS), Earth System Science Interdisciplinary Research Center, University of Maryland, College Park, MD 20740, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sirish","family":"Uprety","sequence":"additional","affiliation":[{"name":"Cooperative Institute for Satellite Earth System Studies (CISESS), Earth System Science Interdisciplinary Research Center, University of Maryland, College Park, MD 20740, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tung-Chang","family":"Liu","sequence":"additional","affiliation":[{"name":"Cooperative Institute for Satellite Earth System Studies (CISESS), Earth System Science Interdisciplinary Research Center, University of Maryland, College Park, MD 20740, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2551-7367","authenticated-orcid":false,"given":"Bin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Cooperative Institute for Satellite Earth System Studies (CISESS), Earth System Science Interdisciplinary Research Center, University of Maryland, College Park, MD 20740, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1589-7098","authenticated-orcid":false,"given":"Xi","family":"Shao","sequence":"additional","affiliation":[{"name":"Cooperative Institute for Satellite Earth System Studies (CISESS), Earth System Science Interdisciplinary Research Center, University of Maryland, College Park, MD 20740, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Cao, C., Zhang, B., Shao, X., Wang, W., Uprety, S., Choi, T., Blonski, S., Gu, Y., Bai, Y., and Lin, L.
