Atmospheric data Community Toolkit (ACT)

AnacondaCloud CodeCovStatus Build Docs

CondaDownloads PyPiDownloads Zenodo ARM

The Atmospheric data Community Toolkit (ACT) is an open source Python toolkit for working with atmospheric time-series datasets of varying dimensions. The toolkit has functions for every part of the scientific process; discovery, IO, quality control, corrections, retrievals, visualization, and analysis. It is a community platform for sharing code with the goal of reducing duplication of effort and better connecting the science community with programs such as the Atmospheric Radiation Measurement (ARM) User Facility. Overarching development goals will be updated on a regular basis as part of the Roadmap .

Please report any issues or feature requests by sumitting an Issue. Additionally, our discussions boards are open for ideas, general discussions or questions, and show and tell!

Version 2.0

ACT now has a version 2.0 release. This release contains many function naming changes such as IO and Discovery module function naming changes. To prepare for this release, a v2.0 has been provided that explains the changes and how to work with the new syntax.

The new release is available on both PyPI and conda-forge.

Please report any bugs of the 2.0 release to the Issue Tracker mentioned in the Important Links section below.

Installation

ACT can be installed a few different ways. One way is to install using pip. When installing with pip, the ACT dependencies found in requirements.txt will also be installed. To install using pip:

pip install act-atmos

The easiest method for installing ACT is to use the conda packages from the latest release. To do this you must download and install Anaconda or Miniconda. With Anaconda or Miniconda install, it is recommended to create a new conda environment when using ACT or even other packages. To create a new environment based on the environment.yml:

conda env create -f environment.yml

Or for a basic environment and downloading optional dependencies as needed:

conda create -n act_env -c conda-forge python=3.12 act-atmos

Basic command in a terminal or command prompt to install the latest version of ACT:

conda install -c conda-forge act-atmos

To update an older version of ACT to the latest release use:

conda update -c conda-forge act-atmos

If you are using mamba:

mamba install -c conda-forge act-atmos

If you do not wish to use Anaconda or Miniconda as a Python environment or want to use the latest, unreleased version of ACT see the section below on Installing from source.

Installing from Source

Installing ACT from source is the only way to get the latest updates and enhancement to the software that have no yet made it into a release. The latest source code for ACT can be obtained from the GitHub repository, https://github.com/ARM-DOE/ACT. Either download and unpack the zip file of the source code or use git to checkout the repository:

git clone https://github.com/ARM-DOE/ACT.git

Once you have the directory locally, you can install ACT in development mode using:

pip install -e .

If you want to install the repository directly, you can use:

pip install git+https://github.com/ARM-DOE/ACT.git

Contributing

ACT is an open source, community software project. Contributions to the package are welcomed from all users.

The latest source code can be obtained with the command:

git clone https://github.com/ARM-DOE/ACT.git

If you are planning on making changes that you would like included in ACT, forking the repository is highly recommended.

We welcome contributions for all uses of ACT, provided the code can be distributed under the BSD 3-clause license. A copy of this license is available in the LICENSE.txt file in this directory. For more on contributing, see the contributor's guide.

Testing

For testing, we use pytest. To install pytest:

$ conda install -c conda-forge pytest

And for matplotlib image testing with pytest:

$ conda install -c conda-forge pytest-mpl

After installation, you can launch the test suite from outside the source directory (you will need to have pytest installed and for the mpl argument need pytest-mpl):

$ pytest --mpl --pyargs act

In-place installs can be tested using the pytest command from within the source directory.
