Evaluating the Accuracy of Precipitation Products Over Utah, United States, Using the Google Earth Engine Platform [PDF]

open access: yesDesert, 2023
Satellite-based precipitation missions can be used to estimate precipitation distribution, especially in areas where there are no rain gauging stations. Nevertheless, these products are still less used because of the lack of accuracy evaluation.
