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.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
