Modelled trends of mean wood density, earlywood density and latewood density (MWDI, EWDI, and LWDI respectively) for the period 1901–2016 for a median tree in terms of tree-ring width, current DBH, and latewood to earlywood ratio of beech (TRW = 1.35 mm, cDBH = 27.45 cm, LER = 0.79), fir (TRW = 1.79 mm, cDBH = 40.02 cm, LER = 0.44) and spruce (TRW = 1.73 mm, cDBH = 36.76 cm, LER = 0.39), in normal hydroclimatic conditions (i.e., SPEI = 0)
