NCDC International Best Track Archive for Climate Stewardship (IBTrACS) Project, Version 3

The International Best Track Archive for Climate Stewardship (IBTrACS) dataset was developed by the NOAA National Climatic Data Center, which took the initial step of synthesizing and merging best track data from all official Tropical Cyclone Warning Centers (TCWCs) and the WMO Regional Specialized Meteorological Centers (RSMCs) who are responsible for developing and archiving best track data worldwide. In recognizing the deficiency in global tropical cyclone data, and the lack of a publically available dataset, the IBTrACS dataset was produced, which, for the first time, combines existing best track data from over 10 international forecast centers. The dataset contains the position, maximum sustained winds, minimum central pressure, and storm nature for every tropical cyclone globally at 6-hr intervals in UTC. Statistics from the merge are also provided (such as number of centers tracking the storm, range in pressure, median wind speed, etc.). The dataset period is from 1848 to the present with dataset updates performed annually in August. The dataset is archived as netCDF files but can be accessed via a variety of user-friendly formats to facilitate data analysis, including netCDF, Shapefile, and CSV formatted files. The update to version 3 data includes new data sources, bug fixes, shapefile-support, discontinued support of ASCII and new variables.

国际气候治理最佳路径档案（International Best Track Archive for Climate Stewardship, IBTrACS）数据集由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）下属的国家气候数据中心开发，该机构率先完成了全球所有官方热带气旋预警中心（Tropical Cyclone Warning Centers, TCWCs）以及世界气象组织（World Meteorological Organization, WMO）区域专业气象中心（Regional Specialized Meteorological Centers, RSMCs）所生成并归档的热带气旋最佳路径数据的合成与合并工作。鉴于全球热带气旋数据存在缺口，且缺乏公开可用的数据集，研发团队推出了IBTrACS数据集，该数据集首次整合了来自10余个国际预报中心的现有最佳路径数据。该数据集以协调世界时（Coordinated Universal Time, UTC）每6小时间隔的频率，记录了全球每一个热带气旋的位置、最大持续风速、最低中心气压以及风暴性质，同时还提供了数据整合过程中的相关统计信息，例如追踪该风暴的预警中心数量、气压波动范围、风速中位数等。数据集的时间跨度为1848年至今，每年8月进行一次例行更新。该数据集最初以netCDF格式归档，但为便于开展数据分析，可通过多种友好格式获取，包括netCDF、Shapefile以及CSV格式文件。该数据集3.0版本的更新内容包括新增数据源、修复程序漏洞、新增Shapefile格式支持，同时停止了对ASCII格式的支持并新增了若干变量。
