long_term_mean

Compute long-term means for NetCDF forcing data.

This script is designed for climate/hydrology forcing datasets that span multiple timesteps (e.g., hourly, daily, monthly, yearly). It supports both “intensive” variables (averaged over time, e.g., temperature) and “extensive” variables (summed over time, e.g., precipitation).

The workflow includes: - optional cropping to a spatial domain, - optional temporal aggregation (hourly → daily, daily → monthly, etc.), - merging multiple input files along the time dimension, - computing the long-term mean (with optional masking thresholds), - saving the result as a NetCDF file.

Intermediate files can be kept or automatically removed depending on options.
