Importantly, we directed the CMS solution vendors to deploy their sensors as they would in practice, rather than directing them to co-locate all of their sensors. This was done intentionally to quantify the impact of different sensor deployments on emission source and rate estimates. Given this experimental setup, we add novelty to existing CMS evaluations by developing methodology to isolate the effect of the sensor platform (e.g., sensor type and arrangement) from the inversion method used to translate raw concentration measurements into source location and emission rate estimates. Results from this comparison highlight important considerations when using CMS to inform mitigation activities (e.g., site visits in response to alerts) and to create measurement-informed inventories at the site-level.
