However, a satellite-based high-resolution (30 m) albedo product which can be used in the polar regions up to 82.5\u00b0 latitude during the summer seasons is lacking. To cover this gap, in this study we calculate satellite-based broadband albedo from Landsat 8 OLI and validate it against broadband albedo measurements from in situ stations located on the Antarctic and Greenland icesheets. The model to derive the albedo from raw satellite data includes an atmospheric and topographic correction and conversion from narrow-band to broadband albedo, and at each step different options were taken into account, in order to provide the best combination of corrections. Results, after being cleaned from anomalous data, show a good agreement with in situ albedo measurements, with a mean absolute error between in situ and satellite albedo of 0.021, a root mean square error of 0.026, a standard deviation of 0.015, a correlation coefficient of 0.995 (p &lt; 0.01) and a bias estimate of \u22120.005. Considering the structure of the model, it could be applied to data from previous sensors of the Landsat family and help construct a record to analyze albedo variations in the polar regions.<\/jats:p>","DOI":"10.3390\/rs13040799","type":"journal-article","created":{"date-parts":[[2021,2,22]],"date-time":"2021-02-22T20:42:51Z","timestamp":1614026571000},"page":"799","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Landsat 8 OLI Broadband Albedo Validation in Antarctica and Greenland"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3108-887X","authenticated-orcid":false,"given":"Giacomo","family":"Traversa","sequence":"first","affiliation":[{"name":"Department of Physical Sciences, Earth and Environment (DSFTA), Universit\u00e0 Degli Studi Di Siena, 53100 Siena, Italy"},{"name":"Department of Environmental Science and Policy (ESP), Universit\u00e0 Degli Studi Di Milano, 20133 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4523-9085","authenticated-orcid":false,"given":"Davide","family":"Fugazza","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Policy (ESP), Universit\u00e0 Degli Studi Di Milano, 20133 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7190-3272","authenticated-orcid":false,"given":"Antonella","family":"Senese","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Policy (ESP), Universit\u00e0 Degli Studi Di Milano, 20133 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2461-2883","authenticated-orcid":false,"given":"Massimo","family":"Frezzotti","sequence":"additional","affiliation":[{"name":"Department of Science, Universit\u00e0 Degli Studi Roma Tre, 00146 Rome, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1016\/j.rse.2006.03.002","article-title":"Reflectance Quantities in Optical Remote Sensing\u2014Definitions and Case Studies","volume":"103","author":"Schaepman","year":"2006","journal-title":"Remote Sens.
