ForestTemp: sub-canopy microclimate temperatures of European forests

Combining more than 1,200 time series of <i>in situ</i> near-surface forest temperatures with topographical, biological and macroclimatic variables in a machine learning model, we predicted the mean monthly offset between sub-canopy temperature at 15 cm above the surface and free-air temperature over the period 2000-2020 at a spatial resolution of 25 m across Europe. This offset was used to calculate mean annual and monthly temperatures for European forest understories.When using any of these layers, please cite: Haesen et al. (2021). ForestTemp –Sub-canopy microclimate temperatures of European forests. Global Change Biology, 00, 1–13. https://doi.org/10.1111/gcb.15892 We have followed the generally accepted definition of BIO1:<br>ForestBIO1 = Annual Mean TemperatureTo mask pixels by the proportion of extrapolation, the file 'extrapolation.tif' can be used.Note that we will provide analoguous maps for minimum/maximum as well as the additional bioclimatic variables (ForestBIO2 - ForestBIO11) in the future. Furthermore, we will also provide the mean monthly temperature maps instead of only the offset maps. All layers are projected in epsg:3035.
