The Earth is arguably the most complex object in the solar system, both in terms of the diversity of materials and compounds as well as the diversity of processes occurring in the Earth system. Comprehensive global measurements are required to investigate, understand and model this complex system that includes processes within and between the biosphere, lithosphere, hydrosphere, cryosphere, and atmosphere...
The global retreat of Earth's cryosphere is the iconic symbol of climate change. Decades of satellite, airborne, and ground observations show clear evidence of increased melting of glaciers and ice sheets, declines in sea ice, and decreasing spring snow cover. This increased melting of cryosphere cover makes Earth more absorptive of sunlight and moves enormous volumes of stored water from frozen state...
In the Northern winter of 2015/16 the Airborne Visible/Infrared Imaging Spectrometer Next Generation (AVIRIS-NG) acquired measurements in India. The measurements were collected as part of a joint campaign between National Aeronautics and Space Administration (NASA) and the Indian Space Research Organization (ISRO) to foster research with imaging spectroscopy in a set of new diverse and unique environments...
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...
