GRIP NOAA GLOBAL HAWK IN-FLIGHT TURBULENCE SENSOR (GHIS) V1

The GRIP NOAA Global Hawk In-Flight Turbulence Sensor (GHIS) dataset was collected by the NOAA Global Hawk In-flight Turbulence Sensor (GHIS) instrument, which measures acceleration at the location of the instrument. Two accelerometers (2g and 5g full scale) are used on each of two measurement axes. The GHIS accelerometers are from the Model 1221 family manufactured by Silicon Designs, Inc. with a frequency response of 400-600Hz. The data system samples each sensor output at 1000 Hz and processes these data to produce mean, maximum, and root-mean square (RMS) values at 10 Hz. The processed data are then broadcast on the Global Hawk internet and brought to the ground via Status and User User Datagram Protocol (UDP) packets. GHIS operated on the Global Hawk for the Genesis and Rapid Intensification Processes (GRIP) experiment and collected data between Aug 15, 2010 - Sep 23, 2010. The major goal was to better understand how tropical storms form and develop into major hurricanes. NASA used the DC-8 aircraft, the WB-57 aircraft and the Global Hawk Unmanned Airborne System (UAS), configured with a suite of in situ and remote sensing instruments that were used to observe and characterize the lifecycle of hurricanes. This campaign also capitalized on a number of ground networks and space-based assets, in addition to the instruments deployed on aircraft from Ft. Lauderdale, Florida ( DC-8), Houston, Texas (WB-57), and NASA Dryden Flight Research Center, California (Global Hawk).

GRIP NOAA 全球鹰机载湍流传感器（GHIS）数据集由NOAA全球鹰机载湍流传感器（GHIS）仪器收集，该仪器测量仪器所在位置的加速度。每个测量轴上均配备了两个加速度计（量程分别为2g和5g）。GHIS加速度计由Silicon Designs, Inc.生产的1221系列模型提供，其频率响应范围为400-600Hz。数据系统以1000Hz的采样率对每个传感器的输出进行采样，并将这些数据进行处理，以产生10Hz的均值、最大值和均方根（RMS）值。处理后的数据随后通过全球鹰互联网广播，并通过状态和用户用户数据报协议（UDP）数据包传送到地面。GHIS在Global Hawk上运行于GRIP（生成和快速增强过程）实验期间，收集了2010年8月15日至2010年9月23日之间的数据。主要目标是更深入地理解热带风暴如何形成并发展成为重大飓风。NASA使用了DC-8飞机、WB-57飞机以及配备有整套原位和遥感仪器的全球鹰无人空中系统（UAS），用于观察和描述飓风的生命周期。此次行动还充分利用了多个地面网络和空间资产，以及部署在佛罗里达州劳德代尔堡（DC-8）、德克萨斯州休斯顿（WB-57）和加利福尼亚州NASA德莱顿飞行研究中心（Global Hawk）的飞机上部署的仪器。
