Integrated Methane Inversion

The Integrated Methane Inversion (IMI) is an open-access cloud computing tool designed for non-expert users to infer methane emissions worldwide at up to 0.25°x0.3125° resolution through analytical inversion of TROPOspheric Monitoring Instrument (TROPOMI) satellite observations with NASA GEOS meteorological data.

How do I Access the IMI?

The IMI is an open-source software project and freely accessible via the AWS Marketplace.

To get started with the IMI, read the documentation on the IMI readthedocs site. Instructions are provided to configure the IMI, run it on AWS, and visualize output.

To view the IMI source code, visit the GitHub repository.
For a high-level scientific description, see the IMI development papers by Varon et al. (2022) and Estrada et al. (2024).

What can I expect?

Total methane emissions in region of interest
Up to 25-km resolution weekly
Sectoral and point source identification
Detailed diagnostics
Error characterization in results

Integral Earth, a new way of accessing the IMI, is currently under development but will be released soon.

We encourage new users to email us at integrated-methane-inversion@g.harvard.edu with a description of your project. This helps us identify priorities for new features and updates.

To request technical support users should open a Github issue

Collaboration

The IMI is a contribution to the NASA Carbon Monitoring System and a collaboration between the Harvard Atmospheric Chemistry Modeling Group (ACMG) and the Netherlands Institute for Space Research (SRON). ACMG development of the IMI is supported in part by ExxonMobil.
