Evaluating Performance of Four Data-Driven Machine Learning Models for Generating Sentinel-2 Albedo at 10 Meters


This article investigates the performance of four data-driven machine learning models for making large-scale maps of surface albedo from Sentinel-2 satellite data at a 10-meter resolution. Albedo maps are valuable for things like climate modeling, agriculture, energy management, and urban heat island management. The four models evaluated in this study are the random forest, the neural network, total variation, and the gradient boosting algorithm. The evaluation process compared each model against the ground truth albedo values taken from Landsat-8 satellite data.
