A CO2-equivalent computer based on static or dynamic CO2-relative global warming potentials coded in Python27, PyGWP.

Project description

PyGWP - A CO2-equivalent computer based on static or dynamic CO2-relative global warming potentials.

Sources

Installation

We are going to use a package management system to install and manage software packages written in Python, namely pip. Open a session in your OS shell prompt and type

pip install pygwp

Or using a non-python-builtin approach, namely git,

git clone git://github.com/lfaucheux/PyGWP.git
cd PyGWP
python setup.py install

Requirements

Use cases

  • Scientific modelling

Example usage:

>>> from PyGWP import GWPBasedCO2eq
>>> dyn_gwp20 = GWPBasedCO2eq(
...     first_year      = 2020,
...     project_horizon = 5,
...     GWP_horizon     = 20,
...     static          = False
... )
>>> ghgs_weight_per_weight_of_output_inventory_flow = {'CO2':1., 'N2O':.0, 'CH4':.0}
>>> co2eq_traj = dyn_gwp20.co2eq_yields_trajectory_computer(
...     ghgs_weight_per_weight_of_output_inventory_flow,
...     as_row_array=False
... )
>>> co2eq_traj['as_array']
array([[1.        ],
       [0.95764081],
       [0.91469171],
       [0.87112496],
       [0.82691128]])
>>> co2eq_traj['as_dict']
{2024: 0.82691127746144444, 2020: 1.0, 2021: 0.95764080833063492, 2022: 0.91469171438570718, 2023: 0.87112496115582216}

>>> co2eq_traj = dyn_gwp20.co2eq_yields_trajectory_computer({'CO2':.0,'N2O':1.,'CH4':.0})
>>> co2eq_traj['as_array']

>>> co2eq_traj = dyn_gwp20.co2eq_yields_trajectory_computer({'CO2':.0,'N2O':.0,'CH4':1.})
>>> co2eq_traj['as_array']

>>> co2eq_traj = sta_gwp20.co2eq_yields_trajectory_computer({'CO2':.0, 'N2O':.0, 'CH4':1.})
>>> co2eq_traj['as_array']
array([[72.2209832, 72.2209832, 72.2209832, 72.2209832, 72.2209832]])
