EMC²: the Earth Model Column Collaboratory
==========================================

:alt: Latest Travis CI build status

An open source framework for atmospheric model and observational column comparison.
Supported by the Atmospheric Systems Research (ASR) program of the United States Department of Energy.

The Earth Model Column Collaboratory (EMC²) is inspired from past work comparing remotely sensed zenith-pointing
measurements to climate models and their single-column model modes (SCMs)
(e.g., Bodas-Salcedo et al., 2008; Lamer et al. 2018; Swales et al. 2018).

EMC² provides an open source software framework to:

1. Represent both ARM measurements and GCM columns in the Python programming
language building on the Atmospheric Community Toolkit (ACT, Theisen et. al. 2019)
and leveraging the EMC² team’s success with Py-ART (Helmus and Collis 2016).
2. Scale GCM outputs (using the cloud fraction) to compare with sub-grid-scale column measurements
using a modular sub column generator designed to run off-line on time series extracted from
existing GCM/SCM output.
3. Enable a suite of comparisons between ARM (and other) column measurements and
the GCM model subcolumns.

Detailed description of EMC² is provided in Silber et al. (GMD, 2022;
https://doi.org/10.5194/gmd-15-901-2022).


Usage
-----

For details on how to use EMC², please see the Documentation (https://columncolab.github.io/EMC2).

Installation
------------

In order to install EMC², you can use either pip or anaconda. In a terminal, simply type either of::

$ pip install emc2
$ conda install -c conda-forge emc2

In addition, if you want to build EMC² from source and install, type in the following commands::

$ git clone https://github.com/columncolab/EMC2
$ cd EMC2
$ pip install .

Requirements
^^^^^^^^^^^^

EMC² requires Python 3.6+ as well as:
* Atmoshperic Community Toolkit (https://arm-doe.github.io/ACT).
* Numpy (https://numpy.org)
* Scipy (https://scipy.org)
* Matplotlib (https://matplotlib.org)
* Xarray (http://xarray.pydata.org)
* Pandas (https://pandas.pydata.org/)
