Dataset to paper "The effects of solar radiation on daily and seasonal stem increment of canopy trees in European temperate old-growth forests."

The dataset contains processed data used in the analysis of the effect of solar irradiance on tree growth on a daily basis in two primary forests located in Czechia (the Boubín Primeval Forest and the Žofín Primeval Forest). The dataset was used in the study titled “The Effects of Solar Radiation on Daily and Seasonal Stem Increment of Canopy Trees in European Temperate Old-Growth Forests.” The data originate from two old-growth forest sites: Boubín (BB) and Žofín (ZF).Data for each site and year are stored in separate files. Data structure /Tree_crown_solar_irradiance Hourly sums of total solar irradiance for each tree crown for one simulated year. /Climate_data Daily climate data extracted from the E-OBS database for both BB and ZF, including:mean air temperature, maximum air temperature, minimum air temperature, precipitation totals, mean daily air humidity, mean daily solar irradiance, and mean daily vapor pressure deficit. /Soil_moisture Daily volumetric soil moisture data extrapolated for both study sites. /Metadata Tree-level metadata including diameter at breast height (DBH) for all trees included in the study at each site. /Stem_data Dendrometer measurements for all trees included in the study.
