CATS-ISS Level 2 Operational Night Mode 7.2 Version 3-01 5 km Profile

CATS-ISS_L2O_N-M7.2-V3-01_05kmPro is the Cloud-Aerosol Transport System (CATS) International Space Station (ISS) Level 2 Operational Night Mode 7.2 Version 3-01 5 km Profile 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-V3-01_05kmPro 是云气溶胶传输系统（Cloud-Aerosol Transport System，CATS）搭载于国际空间站（International Space Station，ISS）的二级业务夜间模式7.2版本3-01 5千米廓线数据产品。该数据集的时间跨度为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，是一款激光雷达遥感仪器，可从国际空间站获取大气气溶胶与云的距离分辨廓线测量数据。CATS的设计在轨运行时长可达三年。该仪器可提供三个波长的垂直廓线数据，运行轨道倾角为51度，距地球表面约230至270英里，重复观测周期接近三天。科研人员首次得以通过每日不同时段观测地球同一地点，从太空研究云与气溶胶的昼夜（即日至夜）效应。CATS二级分层数据产品包含地球物理参数，由一级数据衍生而来，其垂直分辨率为60米，水平分辨率为5千米。
