GRIP HURRICANE IMAGING RADIOMETER (HIRAD) V1

The GRIP Hurricane Imaging Radiometer (HIRAD) V1 dataset contains measurements of brightness temperature taken at 4, 5, 6 and 6.6 GHz, as well as MERRA 2 m wind speed data and JPL MUR Sea Surface Temperature data. The data is provided in netCDF format. The data were collected during the Genesis and Rapid Intensification Processes (GRIP) experiment from September 1, 2010 through September 16, 2010 for storms EARL and KARL. Rain rate and wind speed files may be obtained from the V0 HIRAD dataset. 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.HIRAD 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.

GRIP飓风成像辐射计（HIRAD）V1数据集包含了在4、5、6及6.6 GHz频段测得的亮度温度数据，以及MERRA 2米风速数据和JPL MUR海面温度数据。数据以netCDF格式提供。这些数据是在2010年9月1日至2010年9月16日间，针对风暴EARL和KARL的生成和快速增强过程（GRIP）实验期间收集的。雨率和风速文件可从V0 HIRAD数据集中获取。主要目标是为了更深入地理解热带风暴的形成与发展为强飓风的过程。NASA利用DC-8飞机、WB-57飞机和全球鹰无人机系统（UAS），配备了一套原位和遥感仪器，用于观测和表征飓风的生命周期。HIRAD是一种飓风成像、单极化被动C波段辐射计，具有横跨和沿航向的分辨率，能够通过飞机或基于空间的平台，在暴雨中测量强海洋表面风速。其扫描宽度约为60度。
