LAMASUS - Annual heat fluxes from European forests, grasslands, and croplands simulated over the 20th and 21st century
Description
We provide annual fluxes of sensible and latent heat for the level 1 land use management (LUM) classes forest, grassland, and cropland over Europe. These fluxes were simulated with the land surface model ORCHIDEE v2.2. The provided data cover the historical period, 1901 to 2014 (ORCHIDEE_heat_fluxes_hist_1901_2014.nc), and future projections for 2015 to 2100 under high mitigation scenario SSP-RCP 126 (ORCHIDEE_heat_fluxes_SSP-RCP126_2015_2100.nc) and low mitigation scenario SSP-RCP 370 (ORCHIDEE_heat_fluxes_SSP-RCP370_2015_2100.nc). For simulations over the historical period, we used CRU JRA v2.3 climate forcing data at 0.5° (~50 km) resolution. For future projections, we used the bias corrected IPSL-GCM projections from ISIMIP3b at 1° (~100 km) resolution (Lange & Büchner, 2021). The table below lists the parameters contained in the files together with the level 1 LUM classes and type of heat flux they refer to. List of parameters used for heat budget. Parameter LUM class (Lvl 1) Type of heat flux Forest_H forest sensible Forest_LE forest latent Grass_H grassland sensible Grass_LE grassland latent Crop_H cropland sensible Crop_LE cropland latent The impact of a level 1 LUM transition on the heat fluxes can be calculated as the difference between fluxes for the new level 1 LUM class and fluxes for the old level 1 LUM class for the same years. Note that while future projections represent interannual variability with warmer and colder years, projected warm or cold years do not necessarily coincide with real world warm or cold years. Thus, we suggest to rather use averages of fluxes over 10 or more years to quantify the future impact of LUM transition on local heat fluxes.
