NetCDF水资源提取与聚合

This script extracts hydrological variables (e.g., <i>qtot</i>, <i>qs</i>, <i>qg</i>, <i>airruse</i>) from NetCDF (.<code>nc</code>) files and processes them into annual water resource indicators at the provincial level in China. The workflow includes:Reading NetCDF files and selecting the target variable (<i>qtot</i>, <i>qs</i>, <i>qg</i>, <i>airruse</i>).Converting monthly data into annual sums.Mapping grid-based values to Chinese provinces using a GeoJSON boundary file.Aggregating results by province and adjusting with provincial area data.Exporting the final annual provincial dataset to CSV format.
