A generalized resource-constrained framework for quantifying coupled ecosystem water and carbon fluxes:data source

In this dataset, runoff data from 1927 catchments were obtained from the Global Runoff Data Center (GRDC, http://www.bafg.de/GRDC/EN/Home/homepage_node) and the Catchment Attributes and Meteorology for Large-sample Studies (CAMELS) datasets (Chagas et al., 2020; Coxon et al., 2020; Fowler et al., 2021). CAMELS data sets have precipitation (P) data. In contrast, the GRDC data set does not have P data, which were obtained from the ERA5_land reanalysis dataset (https://cds.climate.copernicus.eu/datasets/reanalysis-era5-land). These catchments have at least 10-year consecutive runoff records without missing a value from 1971 to 2020. The long-term mean evapotranspiration (ET) of each catchment was derived from long-term water balance equation (ET = P - R). To validate the robustness of establish framework, independent observed GPP and ET data from 107 flux stations with records longer than 5 years were also obtained. The complied catchment and flux datasets spanned 46°S to 72°N in latitude, 156°W to 175°E in longitude that represented a wide geographic and climatic distribution.
