Download

The inversion software is available by ftp at /aftp/products/carbontracker/lagrange/src/

The package includes the python scripts, a sample configuration file, a North America landmask, and a netcdf file with a global grid specifying land/ocean cells, which can be used to create a landmask for other domains (see Creating a Landmask File for more information about landmasks).

Requirements

The python code was developed on pretty old versions of python, so it will likely run anywhere. It can run under either python 2 or 3.

• python >= 2.6, python 3.6
• numpy >= 1.4
• scipy >= 0.7
• python netCDF4 module (https://github.com/Unidata/netcdf4-python) The netCDF4 module has additonal requirements. See the docs for more information.
• python configObj module (https://github.com/DiffSK/configobj)

Note

There was a bug in the version 0.12 software for calculating hq (starting in February 2017). This has been fixed in the 0.13 version.
