CMS-based inventory. Figure shows the CMS-based measurement-informed inventories for each site. A separate inventory value is computed for each CMS solution and quantification algorithm, resulting in four inventory values per site. Emission rate estimates from the DLQ algorithm have associated uncertainty, allowing for 95% confidence intervals on the inventories produced using these estimates. The vendor-provided estimates did not have an associated uncertainty, and hence no uncertainty is provided for the inventories created using these estimates. CMS-based inventories are compared against site-level bottom-up inventories provided by the oil and gas operators.
