COMEX

The CO2 and Methane Experiment (COMEX) was a field campaign supporting the mission definition of CarbonSat and HyspIRI. Researchers collected representative airborne remote sensing data, as well as ground-based and airborne in situ data. 

These objectives were addressed by a unique combination of VIS/NIR/SWIR hyperspectral remote sensing airborne instrumentation, TIR hyperspectral instrumentation, and NIR/SWIR spectroscopic instrumentation. COMEX also used in situ airborne and ground-based measurements for validation and interpretation support. 

COMEX demonstrated that methane emissions associated with fossil fuel production activities in the Los Angeles area were of sufficient magnitude and size to be observed by space-based instruments.
