Our Team

Ju is a Ph.D. candidate in Environmental Science & Engineering at the John A. Paulson School of Engineering and Applied Sciences at Harvard University. She developed scalable point source emission estimation approaches for the MethaneAIR and MethaneSAT. Her approaches utilize high-resolution atmospheric simulations and remote sensing observations of greenhouse gases.

Dave is an atmospheric physicist and founder of Crisp Spectra, LLC an environmental science consultancy. Previously his career at NASA’s Jet Propulsion Laboratory focused on development of instruments and numerical models for analyzing light reflected, emitted, and scattered by atmospheres and surfaces of the Earth and other planets. He served as a flight instrument provider and science team member on several Earth, planetary and astrophysics missions. He was the Principal Investigator of the NASA Orbiting Carbon Observatory (OCO) mission and served as the science team leader for NASA’s OCO-2 and OCO-3 missions. He also served as the greenhouse gas lead for the Committee on Earth Observation Satellites (CEOS) Atmospheric Composition - Virtual Constellation (AC-VC) and member of the CEOS/CGMS Working Group on Climate Greenhouse Gas Task Team.

Jonathan is the Deputy Science Principal Investigator and Instrument Principal Investigator for MethaneSAT and is leading the calibration activities for the mission. He is a senior scientist at the School of Engineering and Applied Science at Harvard specializing in remote-sensing of methane and carbon dioxide. He also operates the Boston regional greenhouse gas column network which provides validation data to Earth observing satellites.

Xiong has extensive expertise in satellite retrievals of trace gases and aerosols, and satellite instrument development and calibration. He developed one of the most advanced ozone profile and tropospheric ozone retrieval algorithms for ultraviolet measurements. He is currently the Deputy Principal Investigator for TEMPO, and is the SAO lead on science and algorithms for the MethaneSAT project.

Bingkun has extensive expertise in radiative transfer modelling and remote sensing of sea surface temperature, surface radiative budget, and cryosphere. His work includes analyzing instrument calibration and testing data, and developing calibration methods for MethaneSAT.

Ethan Manninen is a fifth year PhD student in Steve Wofsy's group. Currently, Ethan is trying to understand how the temporal variability in methane plumes affects their contribution to total emissions.

Raia is a Ph.D. candidate in Environmental Science and Engineering at the John A. Paulson School of Engineering and Applied Sciences at Harvard University. Raia’s work leverages the underlying distributions of data within methane plume masks to identify spurious and diffuse plumes in MethaneAIR and MethaneSAT observations. This probabilistic approach to plume classification aims to augment the Level 4 point source QA/QC process.

Jenna is an astrophysicist at the Smithsonian Astrophysical Observatory. She is overseeing the design, construction and testing spectrometers used in the MethaneAIR flight simulations for MethaneSAT, and on applications of MethaneAIR for studies of methane emissions in North America.

Maryann is a research scientist at the John A. Paulson School of Engineering and Applied Sciences at Harvard University. She developed a framework consisting of a sensor array a statistical transport model to quantify methane and carbon dioxise emissions in the Boston urban region. Her work on MethaneSAT includes designing models to quantify methane emissions from point and regional sources.

Eleanor is a Ph.D. candidate in Environmental Science & Engineering at the John A. Paulson School of Engineering and Applied Sciences at Harvard University, where she studies greenhouse gas emissions using remote sensing and works on improving the MethaneSAT product. Her work has included the discovery of the first power plant carbon dioxide emissions seen by MethaneSAT, quality control flags for the MethaneSAT operational pipeline, and the analysis of the MethaneSAT flux product in areas affected by carbon dioxide emissions.

Steven is an Abbott Lawrence Rotch Professor of Atmospheric and Environmental Science; Area Chair for Environmental Science and Engineering. His efforts span the range of processes affecting atmospheric chemistry, including pioneering work on determining regional emissions of methane and carbon dioxide using ground, aircraft, and remote sensing measurements. His studies aim to understand underlying causes for change in atmospheric composition in order to mitigate impacts and provide scientific information for societal decisions.
