HURRICANE AND SEVERE STORM SENTINEL (HS3) GLOBAL HAWK ADVANCED VERTICAL ATMOSPHERIC PROFILING SYSTEM (AVAPS) DROPSONDE SYSTEM V2

The Hurricane and Severe Storm Sentinel (HS3) Global Hawk Advanced Vertical Atmospheric Profiling System (AVAPS) Dropsonde System dataset was collected by the Advanced Vertical Atmospheric Profiling System (AVAPS), built by the National Center for Atmospheric Research (NCAR), which served as the dropsonde system for the Global Hawk aircraft during the HS3 campaign. 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. AVAPS dropsondes provide in-situ, high-vertical resolution measurements of atmospheric variables including pressure, temperature, humidity, geographic location, and winds, providing a vertical profile of the atmospheric conditions. The raw instrument measurement precision is as follows: pressure +-1.0 hPa, temperature +-0.2 degrees C, wind +-1 ms-1, and humidity +-7 percent. The measured information was transmitted via Iridium or Ku-Band satellite to the ground station where the Global Telecommunications System (GTS) performed additional processing for research and operational purposes.

《飓风与强风暴哨兵》(HS3) 全球鹰高级垂直大气廓线系统（AVAPS）探空气球系统数据集，由美国国家大气研究中心（NCAR）构建的先进垂直大气廓线系统（AVAPS）收集而成，该系统作为HS3行动期间全球鹰飞机的探空气球系统。HS3行动的目标包括：评估大规模环境与风暴尺度内部过程之间的相对作用；以及探讨撒哈拉空气层（SAL）在热带风暴形成与增强过程中的争议性作用，以及深对流在风暴核心区的作用。AVAPS探空气球提供对大气变量包括压力、温度、湿度、地理位置和风速等的高垂直分辨率现场测量，从而描绘了大气状况的垂直廓线。原始仪器测量精度如下：压力±1.0百帕，温度±0.2摄氏度，风速±1米/秒，湿度±7%。测量信息通过铱星或Ku波段卫星传输至地面站，全球电信系统（GTS）在此进行进一步处理，以供科研与运营之用。
