Conventional VSWIR imaging spectrometer atmospheric correction evolved from multi-band approaches and generally does not exploit the full spectral measurement. We hypothesize that a pure spectroscopic approach can improve atmospheric inversion accuracy to minimize regional biases in global-scale investigations. Such techniques are pervasive in atmospheric remote sounding disciplines, where Optimal...
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...
We demonstrate real-time model-based atmospheric correction onboard the Next Generation Airborne Visible/Infrared Imaging Spectrometer. We achieve a reduction in processing time from hours or days to seconds by modifying a standard physics-based atmospheric correction algorithm to support real-time execution. We achieved this reduction by modifying the physics-based ATmospheric REMoval algorithm to...
This work presents an automated approach utilizing superpixel segmentation for detecting spectrally Neutral Regions (NR) in hyperspectral images. NRs are often used in planetary geology as spectral divisors to Regions of Interest (ROI), both to enhance key mineralogical signatures and correct for systematic errors such as residual atmospheric distortion. We compare automated NR selections to handpicked...
