We report facility-scale emissions measurements of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ammonia (NH3) from over 200 farms in California, representing 2.4% of the total dairy cow population of the United States. The dairy indu

A large-scale study of methane emissions from well pads was conducted in the Marcellus shale (Pennsylvania), the largest producing natural gas shale play in the United States, to better identify the prevalence and characteristics of superemitters. Ro

Mobile laboratory measurements provide information on the distribution of CH4 emissions from point sources such as oil and gas wells, but uncertainties are poorly constrained or justified. Sources of uncertainty and bias in ground-based Gaussian-deri

We present a methane sensing system based on chirped laser dispersion spectroscopy. The system is capable of actively tracking a drone-based retroreflector at up to 40m distance. The system has also shown sensitivities of 2.3 ppm-m.

We present localization and quantitative concentration analysis of controlled methane releases using chirped laser dispersion spectroscopy (CLaDS) in conjunction with an unmanned aerial vehicle (UAV) in an open-path sensing configuration. The system

International audience; Satellite ammonia (NH3) observations provide unprecedented insights into NH3 emissions, spatiotemporal variabilities and trends, but validation with in‐situ measurements remains lacking. Here, total columns from the Infrared
