Cover Story: Reference evapotranspiration (ET0) is a key variable for irrigation management, yet mapping it over large areas remains difficult where meteorological stations are sparse. Satellite products such as MOD16A2 provide spatially continuous potential evapotranspiration, but they are not directly equivalent to FAO-56 ET0. This paper presents a topography-constrained correction framework tested in Piemonte and Veneto, northern Italy. Station-based PET–ET0 relationships were used to model spatial correction coefficients, with elevation retained as the main topographic proxy. The correction reduced the systematic overestimation of raw MOD16 PET and improved agreement with ground observations, while remaining locally calibrated and regionally interpretable. View this paper
