Model for Estimating Anthropogenic Nutrient diScharges with high Temporal and Spatial resolution dataset (MEANS-ST1.0)

The MEANS-ST1.0 dataset consists of a "Data File" and a "Readme File". The "Data File" serve as the core file, while the "Readme File" provides explanations of abbreviations and units, along with a list of key parameters. Within the data files, we offer three different formats of anthropogenic pollutant discharge datasets. The first format is stored as GeoTIFF files, which can be used in conjunction with GIS software for overall characterization and spatial distribution analysis. The spatial resolution is 1 km, covering three representative years (1980, 2000, and 2020) and providing data on total anthropogenic nitrogen discharges, as well as discharges from five types of anthropogenic pollutant sources: urban residential, rural residential, industry, crop farming and livestock farming. The second format comprises ten NetCDF files, suitable for constructing two-dimensional or multi-dimensional models and conducting data visualization analysis. These files have a spatial resolution of 1 km and contain monthly data for different years (1980, 2000, and 2020) on total TN and TP discharges and five types of anthropogenic pollutant sources. The third format of the dataset is Excel files, supporting the construction of a national integrated model and providing yearly data on anthropogenic pollutant discharges for provincial administrative units, including both total and categorized discharges. The MEANS-ST1.0 dataset incorporates the most comprehensive spatiotemporal dynamic parameters, enabling a fine-grained analysis of the long-term dynamics for China's anthropogenic nutrient discharges from both spatial and temporal perspectives.
