Check out the changes from v03r03 to v03r04.
Please register to be notified of: new releases, data set errors and other important information about IBTrACS.
The following caveats should be considered prior to using IBTrACS:
- BUGS - Dataset errors will be noted on the status page.
- Due to the disparity between storm positions prior to 1970, some tracks during that period may not be properly merged.
- Due to the disparities in time between sources, some dates and times were changed in one source to match another. However, it is not clear which source had the correct time or date. From the original 16,539 storm tracks, only 255 required time adjustments.
NCDC Data set identification
- IBTrACS has been assigned NCDC data set identification (DSI) 9637
