MASS
Modular Aerial Sensing System

The Modular Aerial Sensing System (MASS) is an airborne remote sensing instrument suite operated by the Scripps Institution of Oceanography at the University of California, San Diego. It comprises an airborne topographic lidar, a hyperspectral camera, a longwave infrared (LWIR) camera, an infrared pyrometer, and video and digital camera systems. The lidar maps ocean and land surface topography at 1550 nm, with a 400 kHz repetition rate and a spatial resolution of 50 cm at an altitude of 915 m. The hyperspectral camera is a pushbroom imager operating in the 400-1000 nm spectral range with a resolution of 66 cm. The LWIR camera operates in the 7.5-9.5 μm spectral range with a resolution of 1.06 m or 1.76 m, depending on the scan angle. Video and digital cameras provide imagery at resolutions of 36 cm and 16 cm, respectively. The pyrometer operates in the 9.6-11.5 μm spectral range and provides temperature measurements at 30 Hz.
