CATS-ISS Level 1B Day Mode 7.1 Version 3-00

CATS-ISS_L1B_D-M7.1-V3-00 is the Cloud-Aerosol Transport System (CATS) International Space Station (ISS) Level 1B Day Mode 7.1 Version 3-00 data product. The collection spans from February 10, 2015 through March 21, 2015. CATS, which was launched on January 10, 2015, was a lidar remote sensing instrument that provided range-resolved profile measurements of atmospheric aerosols and clouds from the ISS. CATS was intended to operate on-orbit for up to three years. CATS provides vertical profiles at three wavelengths, orbiting between ~230 and ~270 miles above the Earth's surface at a 51-degree inclination with nearly a three-day repeat cycle. For the first time, scientists were able to study diurnal (day-to-night) changes in cloud and aerosol effects from space by observing the same spot on Earth at different times each day. Level 1B data have been calibrated and annotated with ancillary meteorological data and processed to sensor units.
