Short summary
We developed and field-tested a UAV-based active AirCore for atmospheric measurements of CO2, CH4, and CO. AirCore is an innovative tool that passively samples air using the atmospheric pressure gradient during descent. Here we have taken further steps to change the “active” sampling process with a pump, miniaturize it, and deploy it on a UAV. The active AirCore system opens up a wide variety of opportunities, e.g., quantifying CH4 emissions from wetlands, landfills, other CH4 hot spots.
