Hurricane Satellite (HURSAT) from International Satellite Cloud Climatology Project (ISCCP) B1, Version 6

The Hurricane Satellite (HURSAT) from derived International Satellite Cloud Climatology Project (ISCCP) B1 observations of tropical cyclones worldwide. The B1 data are subsampled observations from the global constellation of geostationary satellites (GOES, Meteosat, GMS, and FY2 series) spanning 1978 through to present year. The data include infrared window, visible and other channels available from the satellite instruments. IBTrACS (International Best Track Archive for Climate Stewardship) best track locations of all global tropical cyclones were temporally interpolated to match the satellite data resolution. The satellite data were then gridded to 8km, with grid centers fixed on the tropical cyclone center of circulation at 3-hour intervals. Data are provided in a convenient NetCDF format which is self-documenting and follows standard storage and metadata conventions. HURSAT version 6 also contains information about the image derived from storm centering algorithms including ARCHER [Wimmer's SSEC algorithm] and the axisymmetric technique. Azimuthal statistics derived from these positions are also provided. Version 6 supersedes all other HURSAT B1 versions.

本数据集为源自国际卫星云气候学计划（ISCCP）B1观测数据的全球热带气旋飓风卫星数据集（HURSAT）。B1数据来自1978年至今的全球地球静止卫星星座（包含GOES、Meteosat、GMS及风云二号系列卫星）的抽样子观测数据集。数据涵盖卫星仪器可获取的红外窗口波段、可见光波段及其他通道观测数据。研究人员将国际最佳路径气候管护档案（IBTrACS，International Best Track Archive for Climate Stewardship）中的全球所有热带气旋最佳路径点位进行时间插值，以匹配卫星数据的分辨率。随后将卫星数据网格化至8公里分辨率，网格中心固定于每3小时一次的热带气旋环流中心。数据以自带元数据文档且遵循标准存储与元数据规范的便捷网络通用数据格式（NetCDF）提供。HURSAT第六版还包含基于风暴中心定位算法（包括ARCHER[威默的SSEC算法]及轴对称技术）得到的图像信息，同时提供基于上述定位结果计算得到的方位统计信息。第六版取代了此前所有HURSAT B1版本。
