Executive editor
This review paper constitutes a tremendous effort reviewing and analyzing a vast body of literature on the evaluation of Satellite Remote Sensing-based evapotranspiration datasets. It is a great road map for this field of research guiding all future such studies toward the use of community-based best practices.

Short summary
Satellite data are increasingly used to estimate evapotranspiration (ET) or the amount of water moving from plants, soils, and water bodies into the atmosphere over large areas. Uncertainties from various sources affect the accuracy of these calculations. This study reviews the methods to assess the uncertainties of such ET estimations. It provides specific recommendations for a comprehensive assessment that assists in the potential uses of these data for research, monitoring, and management.
