[dlebauer]

Summary

Nitrogen (fertilizer) and non‑crop carbon (NCC) inputs need to be generated as statewide parquet datasets to integrate with the monitoring → events → modeling pipeline.

Tasks

• Determine schema consistent with other monitoring products (depends on Harmonize schema for monitoring pipeline outputs #229)
• Generate parquet files for N and NCC inputs.
• Add functions / workflow to PEcAn repository (data.land + workflows/ dir?)
