| Sumario: | <p>The absence of a compiled large-scale catchment
characteristics dataset is a key obstacle limiting the development of large-sample hydrology research in China. We introduce the first large-scale
catchment attribute dataset in China. We compiled diverse data sources,
including soil, land cover, climate, topography, and geology, to develop the
dataset. The dataset also includes catchment-scale 31-year meteorological
time series from 1990 to 2020 for each basin. Potential evapotranspiration
time series based on Penman's equation are derived for each basin. The 4911
catchments included in the dataset cover all of China. We introduced several
new indicators that describe the catchment geography and the underlying
surface differently from previously proposed datasets. The resulting dataset
has a total of 125 catchment attributes and includes a separate HydroMLYR (hydrology dataset for machine learning in the Yellow River Basin)
dataset containing standardized weekly averaged streamflow for 102 basins in
the Yellow River Basin. The standardized streamflow data should be able to
support machine learning hydrology research in the Yellow River Basin. The
dataset is freely available at <a href="https://doi.org/10.5281/zenodo.5729444">https://doi.org/10.5281/zenodo.5729444</a> (Zhen et al., 2021). In
addition, the accompanying code used to generate the dataset is freely
available at
<span class="uri">https://github.com/haozhen315/CCAM-China-Catchment-Attributes-and-Meteorology-dataset</span> (last access: 26 November 2021)
and supports the generation of catchment characteristics for any custom
basin boundaries. Compiled data for the 4911 basins covering all of China
and the open-source code should be able to support the study of any selected
basins rather than being limited to only a few basins.</p> |
