Installing pre-built binaries with conda (Mac OSX, Linux, and Windows)

By far the simplest and recommended way to install climlab is using conda (which is the wonderful package manager that comes with Anaconda Python).

You can install climlab and all its dependencies with:

conda install -c conda-forge climlab

Or (recommended) add conda-forge to your conda channels with:

conda config --add channels conda-forge

and then simply do:

conda install climlab

Binaries are available for OSX, Linux, and Windows. You may need to update your numpy if you are using are using a version prior to 1.11.

For Windows, builds are available for 64-bit versions of Python 3.5 and Python 3.6, and will require numpy 1.14 or later.

Installing from source

If you do not use conda, you can install climlab from source with:

pip install climlab

(which will download the latest stable release from the pypi repository and trigger the build process.)

Alternatively, clone the source code repository with:

git clone

and, from the climlab directory, do:

python install

You will need a Fortran compiler on your system. The build has been tested with both gcc/gfortran and ifort (Linux)

Installing from source without a Fortran compiler

Many parts of climlab are written in pure Python and should work on any system. Fortran builds are necessary for the RRTMG and CAM3 radiation schemes. If you follow the instructions for installing from source (above) without a valid Fortran compiler, you should find that you can still:

import climlab

and use most of the package. You will see warning messages about the missing radiation components.

Source Code

Stables releases as well as the current development version can be found on github:


These are handled automatically if you install with conda.
