climateforcing 0.1.1

pypi

pip install climateforcing

development version

I strongly recommend doing this inside a virtual environment, e.g. conda, to keep your base python installation clean.

Clone the repository, cd to climateforcing and run

pip install -e .[dev]

aprp: Approximate Partial Radiative Perturbation

Generates the components of shortwave effective radiative forcing (ERF) from changes in absorption, scattering and cloud amount. For aerosols, this can be used to approximate the ERF from aerosol-radiation interactions (ERFari) and aerosol-cloud interactions (ERFaci). Citations:

humidity: Conversions for specific to relative humidity and vice versa.

geometry: quick and dirty area-weighted mean

For when you relly want to know the global mean but don’t want to think or download anything much. (Works nicely with aprp).

twolayermodel: two-layer energy balance climate model

Implementation of the Held et al (2010) and Geoffroy et al (2013a, 2013b) two-layer climate model. Thanks to Glen Harris for the original code.
