Integrated Methane Inversion (IMI)

Important

This is a prerelease of the Integrated Methane Inversion (IMI) user guide. These pages contain the most up-to-date and accurate instructions for the IMI, but they are still a work in progress.

Contributions (e.g., suggestions, edits, revisions) would be greatly appreciated. See editing this guide and our contributing guidelines. If you find something hard to understand, let us know!

The Integrated Methane Inversion (IMI) workflow is a cloud-computing tool for quantifying methane emissions by inversion of satellite observations from the TROPOspheric Monitoring Instrument (TROPOMI). It uses GEOS-Chem as forward model for the inversion and infers methane emissions at 25 × 25 km2 resolution.

This site provides instructions for using the IMI, including launching an AWS compute instance, configuring and running an inversion, and analyzing the results with a ready-made jupyter notebook.

Some instructions are specific to the Amazon Web Services (AWS) cloud, but the IMI can also be run on a local compute cluster.
