The goals of this technical development work are to:

  1. Acquire experimental remote sensing and in situ observations of atmospheric CO2, CH4, N2O, CO, boundary layer height, and other key meteorological variables for the Los Angeles megacity to create a benchmark data set with unprecedented realism and spatial and temporal resolution.

  2. Use this benchmark dataset in modeling and observational system simulation experiments (OSSEs) to develop space-based remote sensing strategies optimized to monitor megacity greenhouse gas emissions Our activities will focus on obtaining extensive measurements of CO2 and CH4 as well as other GHGs and important attribution tracers using the unique assets of the Caltech/JPL team:

    • The Caltech solar viewing FTS for continuous daytime measurements of total column CO2, CH4, CO, N2O, C2H6, etc. within the Los Angeles "urban dome"
    • The JPL CLARS instrument that can produce tomographic slant column measurements of CO2, CH4, CO, and N2O by raster scanning across the LA basin from its Mt Wilson vista
    • The JPL CARVE airborne FTS for mobile, variable altitude measurements of CO2, CH4, and CO columns and vertical profiles throughout the LA basin
    • A JPL mobile FTS deployed for 2-6 hour observation periods at various locations throughout the LA basin for continuous daytime total column measurements of CO2, CH4, CO, and N2O
