musica 0.7.1

MUSICA is a Python library for performing computational simulations in atmospheric chemistry.

MUSICA

Multi-Scale Infrastructure for Chemistry and Aerosols

MUSICA is a collection of modeling software, tools, and grids, that allow for robust modeling of chemistry in Earth's atmosphere.

At present the project encompasses these components

• TUV-x

  • A photolysis rate calculator

• MICM

  • Model Independent Chemical Module

Available grids

Pre-made grids for use in MUSICA are available here.

Developer Options

Specifying dependency versions via paramaterization at configure time

Introduced in Pull Request #124, it is possible for developers to specify which versions of various dependencies should be used. These options are currently limited to those dependencies managed via FetchContent. This change allows for more easily testing musica against changes committed in different repositories and branches. The environmental variables introduced are outlined in the following table.

CMake Dependency Variables

Musica Dependency	Repository	Branch, Tag or Hash
Google Test	GOOGLETEST_GIT_REPOSITORY	GOOGLETEST_GIT_TAG
MICM	MICM_GIT_REPOSITORY	MICM_GIT_TAG
TUV-X	TUVX_GIT_REPOSITORY	TUVX_GIT_TAG
PyBind11	PYBIND11_GIT_REPOSITORY	PYBIND11_GIT_TAG

Example Usage

The following examples assume the working directory is a build/ directory inside the musica source directory.

Specifying a different version of tuv-x, to ensure a change won't break anything.

$ cmake .. \
    -DTUVX_GIT_REPOSITORY="https://github.com/WardF/tuv-x.git" \
    -DTUVX_GIT_TAG=test-fix

Specifying a specific version of tuv-x by has, but using the official repository.

$ cmake .. \
    -DTUVX_GIT_TAG=a6b2c4d8745

Citing MUSICA

MUSICA can be cited in at least two ways. The first is to cite the paper that defines the vision of the MUSICA software. The bibtex entry below can be used to generate a citaiton for this.
