CAMP Documentation

CAMP is software for solving multi-phase chemistry in atmospheric models. For a overview of what CAMP can do, check out part 0 of the CAMP tutorial. A description of the CAMP model elements and how to use them follows.

CAMP Input Classes

• Aerosol Phases
• Aerosol Representations
• Chemical Species
• Mechanisms
• Reactions
• Sub-Models

Usage

CAMP uses json input files to load chemical species, mechanisms, aerosol phases, aerosol representations, and sub-models at runtime. How to use CAMP in a new or existing model is described in the Boot CAMP tutorial.

Compiling

You will need to have c and Fortran compilers along with CMake to build the CAMP library. In addition, CAMP has the following dependencies:

Library	Version	Source
SUNDIALS	custom	camp/cvode-3.4-alpha.tar.gz
SuiteSparse	5.1.0	http://faculty.cse.tamu.edu/davis/SuiteSparse/SuiteSparse-5.1.0.tar.gz
json-fortran	6.1.0	https://github.com/jacobwilliams/json-fortran/archive/6.1.0.tar.gz

The SUNDIALS library must be built with the ENABLE_KLU flag set to ON and the KLU library and include paths set according to the SuiteSparse installation.

To install CAMP locally, from the camp/ folder:

mkdir build
cd build
cmake ..
make install

You can also check out ./Dockerfile (or ./Dockerfile.mpi for MPI applications) to see how CAMP is built for automated testing.

Input files

CAMP uses two types of input files:

• File List A json file containing a list of CAMP configuration file names.
• Configuration File One or more json files containing all the CAMP configuration data.

To initialize CAMP , the path to the file list must be passed to the camp_camp_core::camp_core_t constructor. The method by which this is done depends on the host model configuration.
