HURRICANE AND SEVERE STORM SENTINEL (HS3) GLOBAL HAWK CLOUD PHYSICS LIDAR (CPL) V1

The Hurricane and Severe Storm Sentinel (HS3) Global Hawk Cloud Physics Lidar (CPL) dataset includes measurements gathered by the CPL instrument during the HS3 campaign which took place during the hurricane seasons of 2011 through 2014 in the Atlantic Ocean basin region. Goals for HS3 included: assessing the relative roles of large-scale environment and storm-scale internal processes; and addressing the controversial role of the Saharan Air Layer (SAL) in tropical storm formation and intensification as well as the role of deep convection in the inner-core region of storms. The CPL instrument returns information on the radiative and optical properties of cirrus clouds and aerosols at a high temporal and spatial resolution. CPL uses the 355, 532, and 1064 nm channels and has a small field of view, which eliminates multiple scattering; it offers 30 m vertical resolution and 200 m horizontal resolution. The CPL instrument measures the total (aerosol plus Rayleigh) attenuated backscatter as a function of altitude at each wavelength. Data is available in netCDF/CF format, from 2012 - 2014.

《飓风与强风暴哨兵》（HS3）全球鹰云物理激光雷达（CPL）数据集囊括了在2011年至2014年大西洋洋盆地区飓风季节期间，CPL仪器在HS3行动计划中所收集的测量数据。HS3行动计划的目标包括：评估大规模环境与风暴尺度内部过程之间的相对作用；并解决撒哈拉空气层（SAL）在热带风暴形成与增强过程中的争议性角色，以及深对流在风暴核心区域的作用。CPL仪器以高时空分辨率返回关于卷云和气溶胶的辐射和光学特性的信息。CPL采用355、532和1064纳米通道，具有较小的视场，从而消除了多重散射；它提供30米的垂直分辨率和200米的水平分辨率。CPL仪器测量每个波长的总（气溶胶加拉伊尔）衰减后向散射作为高度函数。数据以netCDF/CF格式提供，时间跨度为2012年至2014年。
