Here we show how improvements to our source modeling resulted in better detection of emissions at heights - like storage tanks. These results are verified by blind, third-party testing at METEC in 2025 where Qube’s continuous monitoring detected all releases from heights during the testing period.

What’s New?

• Improved emission event bounding that accounts for source coverage

• Source coverage is calculated based on whether devices are downwind of a particular source at a given time

• We use short term probability to determine if correlation between source coverage and methane readings is coincidence or correlated

• Given high enough probability, we can fill in short gaps and extend emissions

Independent testing at Colorado State University’s METEC Advancing Development of Emissions Detection (ADED) program shows that Qube’s continuous monitoring system reliably detects the leaks that drive most methane emissions at oil and gas sites. Compared with our 2024 campaign, Qube delivered stronger performance under more demanding test conditions.

In this article we walk through the results in four areas: localization, emission rate prediction, detection capability, and quantification. We also link to the final METEC report so you can review the full third-party results.

True false positive alarms are rarely issued by the Qube system. This articles explains what a false positive alarm is in the Qube system, how to make sense of METEC results, and the best practices for responding to potential false positive alarms.

Qube works with industry and academia to conduct blind controlled release test studies conducted by 3rd parties.
