Current IBTrACS Version: v04r00

Introduction

This web page is a portal for IBTrACS data. IBTrACS contains global tropical cyclone best-track data, collected from agencies in every ocean basin. The project has been endorsed by the World Meteorological Organization as the offical archiving and distribution resource for best-track data. The data were collected and processed by the IBTrACS group at the NOAA National Centers for Environmental Information (NCEI) in Asheville, NC.

The IBTrACS Browse pages also provide access to satellite imagery based on infrared window brightness temperatures. The color scale is based on the Dvorak Technique intervals, but modified to include color. The colorbar below provides a mapping of the color imagery to temperature.

The menu at left provides access to IBTrACS data. Data are updated in real-time every Sunday and Thursday. Please contact Dr. Christopher Hennon (chennon_at_unca.edu) if you have any questions or comments about this website. Contact the IBTrACS group at NCEI if you have questions about the data on these pages.
