Remote sensing of greenhouse gases (GHGs) in cities, where high GHG emissions are typically associated with heavy aerosol loading, is challenging due to retrieval uncertainties caused by imperfect characterization of scattering by aerosols. We investigate this problem by developing GFIT3, a full physics algorithm to retrieve GHGs (CO2 and CH4) b...

The California Laboratory for Atmospheric Remote Sensing (CLARS) built by the Jet Propulsion Laboratory (JPL) is an observing facility for the measurement of greenhouse gases and pollutant emissions from sources in the South Coast Air Basin. The facility also serves as a testbed for new optical instruments for future NASA satellite missions. CLA...
