NASA's Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) recently released a new dataset from the CO2 and MEthane eXperiment (COMEX) Project.
This dataset lists flight lines and provides data access links and contextual flight information for a subset of the Airborne Visible InfraRed Imaging Spectrometer - Next Generation (AVIRIS-NG) Facility Instrument Collection that are associated with the COMEX Project. The COMEX Project was carried out May through September, 2014, around the Southern California area. AVIRIS-NG Facility Instrument data are otherwise not replicated in this dataset. The COMEX Project utilized several measurement capabilities, including the AVIRIS-NG airborne facility instrument data, to demonstrate that methane emissions associated with fossil fuel production activities in the Los Angeles, California, area were of sufficient magnitude and size for space-based observations. These lists of the associated COMEX flights from the AVIRIS-NG Facility Instrument provide flight lines and access information for the Level 1B Calibrated Radiance data and the Level 2 Calibrated Reflectance data.
The COMEX campaign, funded bilaterally by NASA and ESA (European Space Agency), supported the mission definition of CarbonSat and HyspIRI by providing representative airborne remote sensing data as well as ground-based and airborne in situ data. The objectives were addressed by a unique combination of VIS/NIR/SWIR hyperspectral remote sensing airborne instrumentation (AVIRIS - Classic, AVIRIS-NG), TIR hyperspectral remote sensing airborne instrumentation (Mako), NIR/SWIR spectroscopic remote sensing airborne instrumentation (MAMAP), as well as in situ airborne (Picarro GHG sensor/analyzer and CIRPAS atmospheric measurements suite) and ground based (AMOG - AutoMObile greenhouse Gas surveyor) 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 for space-based observations. Access COMEX data.
