CATS-ISS Level 2 Operational Night Mode 7.2 Version 3-00 5 km Layer

CATS-ISS_L2O_N-M7.2-V3-00_05kmLay is the Cloud-Aerosol Transport System (CATS) International Space Station (ISS) Level 2 Operational Night Mode 7.2 Version 3-00 5 km Layer data product. This collection spans from March 25, 2015 to October 29, 2017. 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. CATS Level 2 Layer data products contain geophysical parameters and are derived from Level 1 data, at 60m vertical and 5km horizontal resolution.

CATS-ISS_L2O_N-M7.2-V3-00_05kmLay为云气溶胶传输系统（Cloud-Aerosol Transport System，简称CATS）国际空间站（International Space Station，简称ISS）二级操作夜间模式7.2版本3-00的5公里层数据产品。该数据集覆盖时间自2015年3月25日至2017年10月29日。CATS于2015年1月10日发射升空，作为一项激光雷达遥感仪器，旨在从ISS上提供大气气溶胶和云的距平解析剖面测量。CATS原计划在轨运行三年。该系统在地球表面上方约230至270英里范围内，以51度倾角运行，具有近三天的重复周期，并在三个波长下提供垂直剖面数据。科学家们首次能够通过每天不同时间对同一地球位置进行观测，研究云和气溶胶效应的昼夜（日间至夜间）变化。CATS二级层数据产品包含地球物理参数，并从一级数据中推导而来，其垂直分辨率为60米，水平分辨率为5公里。
