Since the network of weather stations in Antarctica is sparse, remote sensing methods have large potential due to their capabilities and accessibility. Based on the MODIS land surface temperature (LST) data,     T  a i r      at the exact time of satellite overpass was modelled at a spatial resolution of 1 km using data from 32 weather stations. The performance of a simple linear regression model to predict     T  a i r      from LST was compared to the performance of three machine learning algorithms: Random Forest (RF), generalized boosted regression models (GBM) and Cubist. In addition to LST, auxiliary predictor variables were tested in these models. Their relevance was evaluated by a Cubist-based forward feature selection in conjunction with leave-one-station-out cross-validation to reduce the impact of spatial overfitting. GBM performed best to predict     T  a i r      using LST and the month of the year as predictor variables. Using the trained model,     T  a i r      could be estimated with a leave-one-station-out cross-validated     R 2     of 0.71 and a RMSE of 10.51      \u2218    C. However, the machine learning approaches only slightly outperformed the simple linear estimation of     T  a i r      from LST (    R 2     of 0.64, RMSE of 11.02      \u2218    C). Using the trained model allowed creating time series of     T  a i r      over Antarctica for 2013. Extending the training data by including more years will allow developing time series of     T  a i r      from 2000 on.<\/jats:p>","DOI":"10.3390\/rs8090732","type":"journal-article","created":{"date-parts":[[2016,9,5]],"date-time":"2016-09-05T10:02:01Z","timestamp":1473069721000},"page":"732","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":110,"title":["Mapping Daily Air Temperature for Antarctica Based on MODIS LST"],"prefix":"10.3390","volume":"8","author":[{"given":"Hanna","family":"Meyer","sequence":"first","affiliation":[{"name":"Environmental Informatics, Faculty of Geography, Philipps-University Marburg, Deutschhausstr. 10, 35037 Marburg, Germany"}]},{"given":"Marwan","family":"Katurji","sequence":"additional","affiliation":[{"name":"Center for Atmospheric Research, University of Canterbury, Christchurch 8020, New Zealand"}]},{"given":"Tim","family":"Appelhans","sequence":"additional","affiliation":[{"name":"Environmental Informatics, Faculty of Geography, Philipps-University Marburg, Deutschhausstr. 10, 35037 Marburg, Germany"}]},{"given":"Markus","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Environmental Informatics, Landcare Research, Hamilton 3240, New Zealand"}]},{"given":"Thomas","family":"Nauss","sequence":"additional","affiliation":[{"name":"Environmental Informatics, Faculty of Geography, Philipps-University Marburg, Deutschhausstr. 10, 35037 Marburg, Germany"}]},{"given":"Pierre","family":"Roudier","sequence":"additional","affiliation":[{"name":"Soils & Landscapes, Landcare Research, Palmerston North 4442, New Zealand"},{"name":"Te Punaha Matatini, A New Zealand Centre of Research Excellence, Private Bag 92019, Auckland 1142, New Zealand"}]},{"given":"Peyman","family":"Zawar-Reza","sequence":"additional","affiliation":[{"name":"Center for Atmospheric Research, University of Canterbury, Christchurch 8020, New Zealand"}]}],"member":"1968","published-online":{"date-parts":[[2016,9,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1689","DOI":"10.1175\/JCLI-D-15-0429.1","article-title":"Antarctic and southern ocean surface temperatures in CMIP5 Models in the context of the surface energy budget","volume":"29","author":"Schneider","year":"2016","journal-title":"J.
