Short summary
Method feasibility and practicality are important considerations for quantifying methane emissions. This study adapted the flux plane mass balance method to a rapidly deployable, operationally flexible, and user-friendly, human-portable telescoping pole-based system. Controlled release test results suggest that the pole method can be applied to moderate height sources at closer downwind distances with performance similar to other widely used mobile quantification methods.
