The Locational Disaggregation Module takes regional forecasts from EVA, SAM, or HEAT and disaggregates them into subregions. Use LDM when an analysis needs locational forecasts that add up to the original regional forecast. The package is maintained under packages/ldm.

Consistency check

The package description states that subregional forecasts add up to the regional forecast.

Consult it for the expected input files and environment setup.
