The primary intent of IBTrACS is to support scientific research efforts.
The IBTrACS data usage policy follows that of the World Data Center for Meteorology (WDC), which employs a policy of full and open access to the data. We have received agreement from the various Regional Specialized Meteorological Centers that provided us with the track data to make the IBTrACS data open for distribution as a contribution to global tropical cyclone research.
Generally, coupled with the WDC policy for data access, we also subscribe to the World Meteorological Organization's Resolution 40 policy regarding such data exchange. Resolution 40 should serve as the guide vis-a-vis any questions concerning the commercial use of the data.
