Previous IBTrACS Dataset Releases

v01cor-r01

All data are identical to v01r01, except for the corrections listed below. Check this area frequently as it may be updated without notice

Release date: 12/23/2008
Corrections which affect storm data:
- ibtracs_tape: Winds are now 10-min winds.
Corrections which do not affect storm data:
- ibtracs_net: Made CF-1.0 compliant
  - Corrected wind speed units: "kn" → "kt" and "knots" → "kt"
  - Corrected scale_factor for variables: lat, lon, pres and wind
Known Bugs:
- Minimum and maximum pressure values are reversed in IBTrACS v01r01 and v01cor-r01. That is, the minimum pressure value from the available centers is reported as the maximum and vice versa. This will be corrected in a future release of IBTrACS.
- Error in BoM intensities - For some storms reported by BoM, intensities were incorrectly ingested into IBTrACS. This only affects cyclones where BoM changed the wind speed units during a storm's lifetime. In such cases, speeds were incorrectly handled (either by not converting m/s to kt or by converting kt to m/s). This bug is present v01r01, too, and is corrected in v02r01.

Release Date 12/15/2008
Version 1.0, Release 01
Bugs:
- ibtracs_tape: Wind speeds in ibtracs_tape files (i.e., HURDAT format) were inadvertantly provided as 1-minute winds. Winds should be corrected back to 10-minute by multiplying wind speeds by 0.88.
- ibtracs_net: files are not CF-compliant
- These bugs are corrected in v01cor-r01 (see above)

Test versions (BETA00x) of the data set were available but are superceded by the release of IBTrACS version 1.
