چکیده
Abstract. This study presents an estimate of historical snow conditions in Iceland and a projection these conditions, given different emission scenarios. Historical were estimated using situ observations from manned meteorological stations over the period 1930–2021 by remotely sensed MODIS instruments 2001–2021. future climate as described each 21 general circulation models (GCM) 5th iteration Coupled Model Intercomparison Project (CMIP5) contained NASA Earth Exchange (NEX) Global Daily Downscaled Projections (GDDP) dataset, used to simulate 1950–2100 under Representative Concentration Pathways (RCP) RCP4.5 RCP8.5 with SNOW-17 model. The results show increase average annual cover frequency (SCF) record detected both (1930–2021) data (2001–2021). Average depth measurements also revealed increasing trend record. Simulated substantial decrease water equivalent (SWE) SCF 1950–2100, more pronounced compared RCP4.5.
