[{"title":"Mid-Holocene climate in Europe simulated with two regional climate models using pollen-based and simulated land cover","summary":"Mid-Holocene climate, ca. 6 thousand years ago (6 ka), was simulated by two regional climate models (RCM) for a European domain (CORDEX EUR-44) at a grid resolution of ~50 km. The two regional models RCA4 (developed at SMHI) and HCLIM38 (developed within the HCLIM consortium) were forced by the global climate model (GCM) EC-Earth. The dataset contains selected output data from the simulations.\r\n\r\nThe 6 ka climate was simulated with different estimates of land cover: one reconstructed land cover based on pollen data, and two estimates simulated by a vegetation model. The pollen-based land cover is reconstructed using the REVEALS model (a model to estimate vegetation from pollen data), statistical analysis and a dataset for estimated past anthropogenic land use (KK10). The RCMs were also run with two different simulations of potential land cover from a dynamical vegetation model (LPJ-GUESS). This gives six simulations of mid-Holocene climate, three with each RCM. In addition, pre-industrial (PI) climate is simulated.\r\n\r\nThe results can be used as a description of mid-Holocene climate. The PI simulations can be used as reference. The simulations can also be used to study the effect of anthropogenic land-cover changes, comparing simulations using potential land cover with simulations using reconstructed land cover. Furthermore, the simulations can be used to estimate the sensitivity of the RCMs to differences in land cover, comparing simulations using different potential land cover.\r\n","citations":"Strandberg G, Lindstr\u00f6m J, Poska A, Zhang Q, Fyfe R, Githumbi E, Kjellstr\u00f6m E, Mazier F, Nielsen A-B, Sugita S, Trondman A-K, Woodbridge J, Gaillard M-J (2022) Mid-Holocene European climate revisited: new high-resolution regional climate model simulations using pollen-based land-cover.
