معرفی
Ehsan Khalefa is a Research Fellow at the University of Portsmouth, affiliated with the Faculty of Science & Health and the School of the Environment and Life Sciences. He is also associated with the Centre of Excellence in Defence, Risk & Resilience. His research focuses on remote sensing applications in environmental studies, particularly vegetation analysis, climate impacts, and topographic modeling. Khalefa has published extensively on topics such as NDVI trends on Mount Kilimanjaro, savanna canopy height retrieval using LiDAR, and GLAS waveform data analysis.
His work combines climatology, ecology, and geospatial technologies to understand environmental changes. Recent studies include a 2025 analysis of climate and topography effects on Kilimanjaro's vegetation using ODIS NDVI data. Earlier contributions include pioneering studies on ICESat-GLAS LiDAR for savanna ecosystems (2010–2013), which remain influential with over 27 citations.
