Description and validation of a carbon monoxide and nitrous oxide instrument for high-altitude airborne science (COMA) Open
In this work, we describe the development of the Carbon monOxide Measurement from Ames (COMA) instrument for measurement of carbon monoxide (CO) and nitrous oxide (N2O) aboard NASA's WB-57 high-altitude research aircraft. While COMA has pr…

Testing the near-field Gaussian plume inversion flux quantification technique using unmanned aerial vehicle sampling Open
Methane emission fluxes from many facility-scale sources may be poorly quantified, potentially leading to uncertainties in the global methane budget. Accurate atmospheric measurement-based flux quantification is urgently required to addres…

Data from the Blackpool testing controlled methane release field campaign of 2018 Open
This dataset contains raw data from Amanda (UAV1) and Phillipa (UAV2), which was acquired during UAV sampling downwind of a controlled methane release in the year 2018. Raw position and wind measurements are provided from on-board UAV1 wit…

Unmanned aerial vehicle observations of cold venting from exploratory hydraulic fracturing in the United Kingdom Open
Unmanned aerial vehicle (UAV) surveys allow for rapid-response near-field sampling, downwind of emission sources, such as gas extraction sites, without the need for site access. UAVs can be used in emission source identification alongside …

Large Uptake of Atmospheric OCS Observed at a Moist Old Growth Forest: Controls and Implications for Carbon Cycle Applications Open
Diurnal and vertical patterns of carbonyl sulfide (OCS) and CO 2 mixing ratios above and within a 60‐m‐tall old‐growth temperate forest are presented. Canopy air from four different heights was sampled in situ using a continuous integrated…
