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.

CATS-ISS_L1B_D-M7.1-V3-00 代表着云气传输系统（Cloud-Aerosol Transport System，简称 CATS）国际空间站（International Space Station，简称 ISS）的 1B 级日模式 7.1 版本 3-00 数据产品。该数据集的收集时间跨度为 2015 年 2 月 10 日至 2015 年 3 月 21 日。CATS，于 2015 年 1 月 10 日发射，是一款激光雷达遥感仪器，能够从 ISS 上对大气气溶胶和云层进行距离分辨的剖面测量。该系统旨在轨运行三年。CATS 在地球表面上方约 230 至 270 英里处，以 51 度的倾角绕地球运行，具有近三天的重复周期，提供三个波长的垂直剖面。首次，科学家们能够通过观察地球上同一地点在不同时间的变化，从空间研究云和气溶胶的昼夜（日间至夜间）变化。1B 级数据经过校准，并附加了辅助气象数据进行了标注，并处理为传感器单位。
