Integrated Methane Inversion

By: Atmospheric Chemistry Modeling Group Latest Version: imi-1.2.1

Product Overview

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 x 0.3125 (25 x 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.
