AToMS

Carnegie's newest operational platform called AToMS (Airborne Taxonomic Mapping System) launched on June 2, 2011. AToMS integrates the world's first Very High Fidelity Visible-Shortwave Infrared (VSWIR) Imaging Spectrometer measuring the 380-2510 nm wavelength range at 5 nm spectral resolution with a dual-laser, waveform Light Detection and Ranging (LiDAR) system, and high-resolution Visible-to-Near Infrared (VNIR) imaging spectrometer.

AToMS provides the world's most advanced measurements of ecosystem chemistry, structure, biomass, and biodiversity, with applications ranging from climate change mitigation to sustainable forest management and habitat conservation. The scientific foundation for biodiversity applications of AToMS in tropical forests can be found at Carnegie Spectranomics.

Alpha (decommissioned)

The CAO Alpha system was decommissioned in 2011. It operated from 2007-2011, and consisted of an integrated Visible-to-Near Infrared (VNIR) imaging spectrometer and waveform Light Detection and Ranging (LiDAR) system. CAO-Alpha made major contributions to studies in California, Colombia, Hawaii, Madagascar, Panama, Peru, and South Africa.

Beta (decommissioned)

The CAO Beta system was comprised of the CAO Light Detection and Ranging (LiDAR) system integrated with the Airborne Visible and Infrared Imaging Spectrometer (AVIRIS). This mode provided spectral information spanning the 380-2510 nm wavelength region, along with high-resolution LiDAR data. The CAO Beta system was the research testbed for the CAO AToMS airborne system. CAO Beta operated in California and Hawaii.

The CAO is operated onboard a Dornier 228 aircraft with customized avionics, instrument facilities and sensor mounts. The CAO aircraft is capable of reaching all tropical regions of the world.
