2015 CAO Spectrometer Report: Generating Novel Measurements of Earth

Imaging Spectroscopy

We are pleased to announce the release of the 2015 CAO-3 Calibration and Validation Report for the Airborne Taxonomic Mapping System (AToMS) imaging spectrometers.

A new report describing the calibration and validation of the CAO Visible-to-Shortwave Infrared (VSWIR) and Visible-to-NearInfrared (VNIR) imaging spectrometers is available on the CAO Publications page. This report provides technical information establishing the performance and readiness of the CAO high-fidelity imaging spectrometers for the 2015 flight season.

The report establishes the extremely high performance of the CAO spectrometers, which are used to map a variety of materials on the Earth’s surface ranging from plant chemicals and biodiversity, to soils, geologic substrates, snow and ice, and atmospheric composition. The findings are presented for community transparency.

Imaging spectroscopy has a growing contribution to Earth and planetary science, but very few spectrometers have been devised to provide spectral data spanning the 400 to 2500 nm wavelength range with the precision and accuracy required for quantitative mapping of the Earth’s surface. The CAO VSWIR spectrometer is arguably the most advanced imaging system ever built in the civil or military sectors. Its performance is the result of decades of painstaking research and development among colleagues from the Jet Propulsion Laboratory, Analytical Imaging and Geophysics LLC, and the Carnegie Institution for Science.
