Carbon dioxide (CO2) emissions from combustion sources are uncertain in many places across the globe. Satellites have the ability to detect and quantify emissions from large CO2 point sources, including coal-fired power plants. In this study, we rout

A reduction in anthropogenic methane emissions is vital to limit near-term global warming. A small number of so-called super-emitters is responsible for a disproportionally large fraction of total methane emissions. Since late 2017, the TROPOspheric

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 9617-9646 (2022)

We review the capability of current and scheduled satellite observations of atmospheric methane in the shortwave infrared (SWIR) to quantify methane emissions from the global scale down to point sources. We cover retrieval methods, precision and accu

The 2019 methane budget and uncertainties at 1° resolution and each country through Bayesian integration Of GOSAT total column methane data and a priori inventory estimates

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 6811-6841 (2022)

We use optimal estimation (OE) to quantify methane fluxes based on total column CH4 data from the Greenhouse Gases Observing Satellite (GOSAT) and the GEOS-Chem global chemistry transport model. We then project these fluxes to emissions by sector at

Methane emissions decline from reduced oil, natural gas, and refinery production during COVID-19

Autor: A K Thorpe, E A Kort, D H Cusworth, A K Ayasse, B D Bue, V Yadav, D R Thompson, C Frankenberg, J Herner, M Falk, R O Green, C E Miller, R M Duren

Publikováno v: Environmental Research Communications, Vol 5, Iss 2, p 021006 (2023)

In the summer of 2020, the AVIRIS-NG airborne imaging spectrometer surveyed California’s Southern San Joaquin Valley and the South Bay (Los Angeles County) to identify anthropogenic methane (CH _4 ) point source plumes, estimate emission rates, and

Publikováno v: Atmospheric Measurement Techniques, Vol 12, Pp 5655-5668 (2019)

We examine the potential for global detection of methane plumes from individual point sources with the new generation of spaceborne imaging spectrometers (EnMAP, PRISMA, EMIT, SBG, CHIME) scheduled for launch in 2019–2025. These instruments are des

Detecting high-emitting methane sources in oil/gas fields using satellite observations

Autor: D. H. Cusworth, D. J. Jacob, J.-X. Sheng, J. Benmergui, A. J. Turner, J. Brandman, L. White, C. A. Randles

Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 16885-16896 (2018)

Methane emissions from oil/gas fields originate from a large number of relatively small and densely clustered point sources. A small fraction of high-mode emitters can make a large contribution to the total methane emission. Here we conduct observati

Aerosol trends as a potential driver of regional climate in the central United States: evidence from observations

Publikováno v: Atmospheric Chemistry and Physics, Vol 17, Pp 13559-13572 (2017)

In situ surface observations show that downward surface solar radiation (SWdn) over the central and southeastern United States (US) has increased by 0.58–1.0 Wm−2 a−1 over the 2000–2014 time frame, simultaneously with reductions in US aero
