In the absence of in situ measurements, remote sensing platforms can indirectly measure water temperature over time and space. The Earth Resources Observation and Science (EROS) Center has processed archived Landsat imagery into analysis ready data (ARD), including Level-2 Provisional Surface Temperature (pST) estimates derived from the Landsat 4\u20135 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8 Thermal Infrared Sensor (TIRS). We compared in situ measurements of water temperature within the Yukon River in Alaska with 52 instances of pST estimates between June 2014 and September 2020. Agreement was good with an RMSE of 2.25 \u00b0C and only a slight negative bias in the estimated mean daily water temperature of \u22120.47 \u00b0C. For the 52 dates compared, the average daily water temperature measured by the USGS streamgage was 11.3 \u00b0C with a standard deviation of 5.7 \u00b0C. The average daily pST estimate was 10.8 \u00b0C with a standard deviation of 6.1 \u00b0C. At least in the case of large unstratified rivers in Alaska, ARD pST can be used to infer water temperature in the absence of or in tandem with ground-based water temperature monitoring campaigns.<\/jats:p>","DOI":"10.3390\/rs13122394","type":"journal-article","created":{"date-parts":[[2021,6,20]],"date-time":"2021-06-20T21:50:15Z","timestamp":1624225815000},"page":"2394","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Comparison of Historical Water Temperature Measurements with Landsat Analysis Ready Data Provisional Surface Temperature Estimates for the Yukon River in Alaska"],"prefix":"10.3390","volume":"13","author":[{"given":"Carson A.","family":"Baughman","sequence":"first","affiliation":[{"name":"U.S. Geological Survey Alaska Science Center, Anchorage, AK 99508, USA"}]},{"given":"Jeffrey S.","family":"Conaway","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey Alaska Science Center, Anchorage, AK 99508, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,19]]},"reference":[{"key":"ref_1","unstructured":"Reid, G.K.
