IBTrACS

International Best Track Archive for Climate Stewardship

Overview

I designed and developed the International Best Track Archive for Climate Stewardship (IBTrACS), the authoritative global repository for tropical cyclone data. As the original architect of this foundational dataset, I created a system that consolidates and standardizes tropical cyclone best track data from all Regional Specialized Meteorological Centers (RSMCs) and other operational forecast centers worldwide.

IBTrACS has become the definitive source for historical tropical cyclone information, serving as the world’s most complete and reliable collection of tropical cyclone best track data. The dataset spans the entire satellite era and earlier, providing researchers, operational forecasters, and risk assessment professionals with consistent, quality-controlled tropical cyclone records from all ocean basins.

Impact

  • 3,250+ citations in scientific literature, making it one of the most widely referenced climate datasets
  • Official WMO dataset recognized as the authoritative global tropical cyclone archive
  • IPCC assessments rely on IBTrACS for tropical cyclone climate change analysis
  • Operational use by National Hurricane Center (NHC) and international forecast centers
  • Reinsurance industry standard for catastrophe modeling and risk assessment
  • Private sector foundation for insurance underwriting and catastrophe bonds

This widespread adoption reflects the dataset’s reliability and the depth of expertise invested in its development.

Data Access

The IBTrACS dataset is actively maintained by NOAA NCEI and freely available to the global community:

  • Primary Data Portal: NOAA NCEI IBTrACS Website
  • Data Downloads: Available in multiple formats (NetCDF, CSV, shapefile) via HTTPS access
  • Coverage: Global, all ocean basins (Atlantic, Eastern Pacific, Western Pacific, North Indian, Southern Hemisphere)
  • Temporal Span: 1842–present (varies by basin)
  • Update Frequency: Regularly updated with new tropical cyclone data from all operational centers

Applications

IBTrACS serves diverse user communities across multiple sectors:

Climate Research

  • Long-term tropical cyclone trend analysis
  • Climate change impact studies
  • Basin-scale variability and teleconnection research
  • Historical storm reconstruction and reanalysis

Technical Details

IBTrACS employs sophisticated data integration methodologies:

  • Multi-agency Integration: Consolidates data from all Regional Specialized Meteorological Centers and operational forecast centers worldwide
  • Quality Control: Comprehensive validation procedures to ensure consistency across different data sources and formats
  • Standardization: Harmonizes disparate formats and conventions into a unified, consistent dataset
  • Historical Continuity: Preserves historical data while incorporating modern observations
  • International Coordination: Ongoing collaboration with WMO, operational centers, and research institutions

The dataset represents decades of careful curation and expertise in tropical cyclone climatology, establishing IBTrACS as the global standard for tropical cyclone data.
