Characterising the EUREC4A field campaign environment

eurec4a_environment

The aim of this git repository is collect tools and ideas for characterising the atmospheric environment during the EUREC4A field campaign.

See below for how to work with the module or the list of variables that are (being) implemented

Working with eurec4a_environment

Depending on whether you want to a) just use the module or b) contribute to it you can either install with pip directly or check out a copy locally and make that available in your PYTHONPATH

a) Installing with pip

eurec4a_environment isn't yet on pipy, but you can install it directly from github:

pip install git+https://https://github.com/eurec4a/eurec4a-environment#egg=eurec4a_environment

b) Cloning and using a local copy

To develop on eurec4a_environment you'll need to make a local copy by cloning this repository. The best thing is to create your own fork first (so you can push your branches to there and make pull-requests from there) and then clone that

  1. Create your own fork of eurec4a_environment

  2. Clone your fork to your local computer

$> git clone https://github.com/{your-github-username}/eurec4a-environment
  1. Install your local copy with pip in developer mode (so that any changes you make to the source-code locally will be available when you import eurec4a_environment). Make sure to have the python environment active that you want to install this module into:
$> cd eurec4a-environment
$> pip install --editable .

Variables, definitions and source data

NOTE: The tables below are likely out-of-date (but will be updated at the end of the hackathon), see the project document for a more up-to-date list and discussion.

Column-based scalars

(could be averaged over flight, full-circle, single sounding etc)

variable description definition data sources implementation
h_BL boundary layer depth numerous definitions (add links) thermodynamic profiles
