Temporal and Spatial Variability in Contemporary GreenlandWarming (1958-2020)
In this study, 2-m or near-surface air temperature (T2m) products from atmospheric reanalysis ERA5 and the regional climate model RACMO2.3p2 over Greenland are compared with observations from staffed stations and AutomatedWeather Stations (AWS). The results show the following: 1) Greenland experienc...
