The AToMS instrument suite was designed by Greg Asner of the Carnegie Institution and manufasctured by many sub-contractors. NASA/JPL (Jet Propulsion Laboratory), Pasadena, CA is the prime contractor for the VSWIR imaging spectrometer. The AToMS instrument package is comprised of three custom-built instruments: 1) VSWIR (Visible and Shortwave Infrared) imaging spectrometer, measuring reflected solar radiance from 380-2500 nm in 5 nm increments (> 400 bands); the spatial resolution is 0.5-2.0 m, depending on the flight altitude. 2) Multi-pulse waveform LiDAR (Light Detection and Ranging), a high-resolution waveform LiDAR system providing contiguous ground coverage and full three-dimensional imaging. The instrument measures up to 400,000 pulses/s with dual laser beams; 0.5-1.0 m spatial resolution. 3) VNIR (Visible Near Infrared) zoom imaging spectrometer, a high-fidelity imaging system providing contiguous spectral signatures of targets in VNIR. The instrument measures reflected solar radiance from 367-1060 nm in 5 nm increments; 0.5-1.0 m spatial resolution.
