Hannah Nesser

Hannah Nesser is interested in the use of satellite observations to quantify greenhouse gas fluxes at the spatial and temporal resolutions needed to support climate policy. Her Ph.D. research used methane observations from the Tropospheric Monitoring Instrument (TROPOMI) aboard the Sentinel-5 Precursor satellite to quantify methane emissions over North America at 25 km x 25 km resolution, allowing improved understanding of methane emissions from individual states, urban areas, and landfills. The tools she developed for this analysis allowed her to quantify the information content of the satellite observations, improving the understanding of the uncertainties of the resulting methane estimates. At JPL, she will be building on these methods to quantify carbon dioxide fluxes using observations from the Orbiting Carbon Observatories (OCO-2 and OCO-3).
