Two Decades of Optical and Thermal Variability in Lake Nasser: A Multi-Variable MODIS Assessment on a 5 km Analysis Grid (2005–2025)
Multi-decadal trajectories of large arid-zone reservoirs are seldom described by integrated satellite observation. This study characterises the optical and thermal variability of Lake Nasser, Egypt, over 2005–2025. Eight monthly MODIS indicators—NDVI, EVI, NDWI, NDTI, a near-infrared reflectance index, white-sky albedo...
