The method was originally developed for cultivated species based on lysimeter measurements of potential evapotranspiration. Not many applications to natural vegetated areas exist due to the lack of available data for these species. In this paper we investigate the potential of using evapotranspiration measurements acquired by micrometeorological stations for the definition of crop coefficient functions of natural vegetated areas and extrapolation to ungauged sites through remotely sensed data. Pastures, deciduous and evergreen forests have been considered and lower crop coefficient values are found with respect to FAO data.<\/jats:p>","DOI":"10.3390\/s17112664","type":"journal-article","created":{"date-parts":[[2017,11,20]],"date-time":"2017-11-20T11:35:45Z","timestamp":1511177745000},"page":"2664","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Assessing Crop Coefficients for Natural Vegetated Areas Using Satellite Data and Eddy Covariance Stations"],"prefix":"10.3390","volume":"17","author":[{"given":"Chiara","family":"Corbari","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, Politecnico di Milano, Piazza Leonardo da Vinci, 32, 20133 Milan, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6850-0883","authenticated-orcid":false,"given":"Giovanni","family":"Ravazzani","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Politecnico di Milano, Piazza Leonardo da Vinci, 32, 20133 Milan, Italy"}]},{"given":"Marta","family":"Galvagno","sequence":"additional","affiliation":[{"name":"Environmental Protection Agency of Aosta Valley, Climate Change Unit, 11100 Aosta, Italy"}]},{"given":"Edoardo","family":"Cremonese","sequence":"additional","affiliation":[{"name":"Environmental Protection Agency of Aosta Valley, Climate Change Unit, 11100 Aosta, Italy"}]},{"given":"Marco","family":"Mancini","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Politecnico di Milano, Piazza Leonardo da Vinci, 32, 20133 Milan, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2017,11,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1016\/j.jhydrol.2004.10.024","article-title":"Evaluation of three complementary relationship evapotranspiration models by water balance approach to estimate actual regional evapotranspiration in different climatic regions","volume":"308","author":"Xu","year":"2005","journal-title":"J.
