The Airborne Methane Plume Spectrometer (AMPS) is a mature instrument concept that is ready for development at the Jet Propulsion Laboratory (JPL). At its core is a novel high-resolution imaging spectrometer that records solar reflected light between 1.99 and 2.42 pm at 1 nm resolution, including strong methane (CH4) bands in the short-wave infrared. The push-broom spectrometer will leverage recent...
Optical absorbers based on vertically aligned multi-walled carbon nanotubes (MWCNTs), synthesized using electric-field assisted growth, are described here that show an ultra-low reflectance, 100X lower compared to Au-black from wavelength λ ∼ 350 nm – 2.5 µm. A bi-metallic Co/Ti layer was shown to catalyze a high site density of MWCNTs on metallic substrates and the optical properties of the absorbers...
Carbon dioxide (CO2) and methane (CH4) are the two primary anthropogenic greenhouse gases contributing to positive radiative forcing that causes global warming. Plumes emitted from point sources such as power plants (CO2) and fossil fuel production (CH4) may be detectable using high spectral and spatial resolution airborne imaging spectrometer data. We used the MODTRAN radiative transfer model to...
