Integrated Methane Inversion

The Integrated Methane Inversion (IMI) is a user-friendly, cloud-based facility for estimating regional methane emissions by analytical inversion of satellite observations from the TROPOspheric Monitoring Instrument (TROPOMI). It enables researchers and stakeholders to infer methane emissions at 0.25° × 0.3125° (≈ 25 × 25 km2) resolution from TROPOMI satellite data resident on the Amazon Web Services (AWS) cloud, without requiring expert knowledge of inverse methods or cumbersome data download.

The IMI uses the GEOS-Chem 3-D chemical transport model, also resident on AWS, as the forward model for the inversion.

For more information, please visit https://imi.seas.harvard.edu. Several Members in the group have compiled a google doc guide for setting up and running the IMI on cannon.
