SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires numpy, ki_tools_common.

What problem does it solve?

Automates the end-to-end DayCent workflow from site setup through data extraction, reducing manual orchestration and minimizing configuration errors in soil-ecosystem flux modelling.

Core Features & Use Cases

  • End-to-end DayCent pipeline: builds site files (<site>.100, sitepar.in, soils.in, outfiles.in), generates daily weather files, runs equilibrium spin-up, base history, and treatment, and provides extraction hooks for outputs.
  • Validation, diagnostics and reuse: integrates preflight checks, diagnostic triplets, and a structured validation stage to ensure scientifically plausible results and reproducible workflows.
  • Output extraction and analysis: supports DDlist100-based variable extraction and parse_daycent_output-based tidying and metrics against observed data for streamlined analysis.

Quick Start

Run DayCent workflow by configuring a run directory with a Wooster-like template and executing the three-stage run (eq → base → treat) followed by extraction to produce tidy outputs for analysis.

FAQPage Schema
How do I automate the DayCent earth system model workflow from site setup to data extraction?

You can automate the DayCent earth system model workflow by orchestrating site file creation, spin-up, history, treatment runs, and output extraction into a single end-to-end pipeline, reducing manual configuration and errors in soil-ecosystem flux modeling.

What is the process for running a DayCent equilibrium spin-up before treatment simulations?

The DayCent equilibrium spin-up process enforces preflight checks and ACEQ-driven iterations to stabilize soil variables before executing base history and treatment runs for cropland flux studies.

How do I extract and tidy specific output variables from DayCent model runs for validation?

Extract output variables from DayCent model runs using DDlist100-based extraction hooks and parse_daycent_output tidying to format metrics against observed data for streamlined analysis.

Does this DayCent pipeline support validation and diagnostics for earth system research?

Yes, the DayCent pipeline supports earth system research validation by integrating preflight checks, diagnostic triplets, and a structured validation stage to ensure scientifically plausible and reproducible results.

What site configuration files do I need to prepare for a DayCent cropland flux simulation?

Prepare DayCent cropland flux simulations by configuring a run directory with site files like <site>.100, sitepar.in, soils.in, and outfiles.in, along with daily weather forcing files.

Why do I need preflight checks and strict input validation in soil-ecosystem flux modeling?

Preflight checks and strict input validation in soil-ecosystem flux modeling minimize configuration errors and ensure scientifically plausible results by catching invalid inputs before executing spin-up and treatment runs.
