Atmospheric Chemistry Box Modeling with KPP + BOXMOX

A practical, hands-on guide to building and running atmospheric chemistry box models using KPP (Kinetic PreProcessor) and BOXMOX. This repository is designed to take you from zero to fully working simulations, with clear examples and organized chapters.

📌 What’s Inside

✅ Introduction to box models

✅ How KPP generates chemistry solvers

✅ How BOXMOX uses those solvers in simulations

✅ Step-by-step tutorials with increasing complexity

✅ Realistic chemical schemes and multi-scenario examples

You’ll find:

  • Basic KPP mechanism setup
  • Writing .eqn files from scratch
  • KPP compilation and solver generation
  • Linking KPP outputs with BOXMOX
  • Running simulations with different reaction schemes
  • Visualizing and analyzing results

🚀 Getting Started

Requirements

  • Python 3.x (for plotting/processing)
  • BoxModel (BOXMOX)
  • KPP installed and working on your machine
  • Standard build tools: gcc, make, etc.

Quick Start

git clone https://github.com/nidhispace/ChemBox-Lab.git
cd ChemBox-Lab/

# Example: Compile a simple mechanism
cd docs/examples/simple_NOx_example/
make
./boxmodel

Then open the output results in your plotting tool of choice (example Python script included).

🧪 Example Applications

  • NOx chemistry under sunlight
  • Isoprene oxidation scheme
  • VOC + NOₓ pollution scenario
  • Sensitivity analysis and emission perturbations

More examples will be added over time.

🎯 Goal of This Project

To create a clear, accessible learning resource for:

  • Students starting with atmospheric chemistry modeling
  • Researchers needing quick reference setups
  • Anyone wanting to test chemistry schemes without full 3-D models

✅ Status

📚 Still under Development
