A past and present perspective on the European summer vapour pressure deficit

Here, we present the first gridded reconstruction of the European summer vapour pressure deficit (VPD) for the past four centuries (see https://doi.org/10.5194/essd-2022-47 for the study). The gridded reconstruction is based on 26 European tree-ring oxygen isotope records and is performed using a Random Forest approach.  Furthermore, we provide summer VPD data derived from 20CRV3 for the period 1836 to 2015 (Slivinski et al., 2019). 

The data is structured as follows:

VPD_final_nested_reconstruction.nc -> contains the summer VPD reconstruction for the past 400 years

CE_final_*_.nc -> provides the Coefficient of Efficiency metric for each time slice of the rec. (Nash and Sutcliffe, 1970)

VPD_20CR_JJA.nc -> VPD data derived from 20CRV3 for the period 1836 to 2015 (Slivinski et al., 2019)
