GRIP HURRICANE IMAGING RADIOMETER (HIRAD) V0

The GRIP Hurricane Imaging Radiometer (HIRAD) dataset was collected by the HIRAD instrument, which is a hurricane imaging, single-polarization passive C-band radiometer with both cross-track and along-track resolution that measures strong ocean surface winds through heavy rain from an aircraft or space-based platform. Its swath width is approximately 60 degrees in either direction. V0 data contains brightness temperature measurements taken at a 5 GHz frequency. Rain rate and wind speed files for Hurricane Earl have been added to the collection. HIRAD data was collected for storms Earl and Karl during the Genesis and Rapid Intensification Processes (GRIP) experiment from September 1, 2010 through September 16, 2010. The major goal was to better understandhow tropical storms form and develop into major hurricanes. NASA used the DC-8 aircraft, the WB-57 aircraft and the Global Hawk Unmanned AirborneSystem (UAS), configuredwith a suite of in situ and remote sensing instruments that were used to observe and characterize the lifecycle of hurricanes.

GRIP飓风成像辐射计（HIRAD）数据集由HIRAD仪器收集，该仪器是一款具有横跨轨道和沿轨道分辨率的飓风成像、单极化被动C波段辐射计，能够通过飞机或太空平台在强降雨条件下测量海洋表面的强烈风速。其扫描宽度约为60度。V0数据包含在5吉赫兹频率下采集的亮度温度测量值。数据集中增加了针对飓风Earl的降雨率和风速文件。HIRAD数据是在2010年9月1日至2010年9月16日进行的GRIP（生成与快速增强过程）实验期间，针对风暴Earl和Karl收集的。主要目标是更好地理解热带风暴的形成与发展过程。NASA利用DC-8飞机、WB-57飞机以及配备有全套现场和遥感仪器的全球鹰无人机系统（UAS），对这些仪器进行配置，以观察和表征飓风的生命周期。
