Upcoming Seminars


Methane sensing from space at the facility scale – Early results from GHGSat-C1

Speaker: Jason McKeever, GHGSat, Inc.
Dr. Jason McKeever is Science and Systems lead at the GHGSat, a Canadian company that aims to monitor emissions of greenhouse gases and eventually air quality gases with micro-satellites. Dr. McKeever earned his PhD in physics from Caltech. Prior to joining GHGSat, Dr. McKeever worked at a start-up company, Entanglement Technologies, developing laser spectrometers for trace gas measurements of VOCs for field applications.
Date/Time: Wednesday, December 2, 2020 02:00 PM
Location: Webinar:
GHGSat recently launched its second satellite (GHGSat-C1, or “Iris”) for methane detection andquantification from individual industrial facilities. Our compact (< 15 kg) satellite instruments havespatial resolution below 50 m, which enables (a) unparalleled fine-resolution plume imaging (b)attribution of emissions to specific infrastructure and (c) sensitivity to point sources of order 100 kg/hrand higher. While the first two capabilities (a, b) were achieved with our demonstration satellite(GHGSat-D “Claire”, operating since 2016), our next generation instrument design was required toapproach our target detection threshold (c). In this seminar I will explain the GHGSat instrument designand retrievals at a conceptual level. I will then present example retrievals from a range of sites aroundthe world under various conditions, including controlled releases, oil and gas production areas, landfillsand coal mines. I will also discuss challenges with the retrievals, ongoing optimizations, calibration andvalidation, and our plans for the GHGSat constellation.
