C-TRAILv1.0 is based on CMAQv5.2 (you can find all the changes in the /CCTM/scripts/ and /CCTM/src/)

If you are planning to run the C-TRAIL model, you need to use CMAQ's tutorials.

C-TRAIL/CMAQ combines current knowledge in atmospheric science and air quality modeling with multi-processor computing techniques in an open-source framework to deliver fast, technically sound estimates of ozone, particulates, toxics, and acid deposition.

C-TRAIL Repository Guide

Source code and scripts are organized as follows:

• CCTM: code and scripts for running the 3D-CTM at the heart of C-TRAIL.
• DOCS: CMAQ User's Guide, developers guidance, tutorials and known issues.
• PREP: Data preprocessing tools for important input files like initial and boundary conditions, etc.
• POST: Data postprocessing tools for aggregating and evaluating CMAQ output products (e.g. Combine, Site-Compare, etc)
• TUTORIALS: Short tutorials provide examples of different CMAQ features.
• UTIL: Utilities for generating code and using CMAQ (e.g. chemical mechanism generation, IO-API, etc)

Documentation

Release notes and Code documentation are included within this repository (they are version-controlled along with the code itself).
