Dear Sir/Madam, My colleague downloaded the IBTrACS data in 2021, and I downloaded it from the same link in 2024. We noticed discrepancies in the reports, which we attribute to maintenance updates, especially in recent years. However, we observed a change in the reporting of the Cempaka Tropical cyclone (2017), which was listed as -1 in the USA SSHS index in the 2021 report but is now listed as -5 in the 2024 report. We are curious about the reasons behind this discrepancy. Thank you in advance for your assistance.

Hi-

CEMPAKA 2017 (2017325S10112) doesn't actually contain any data from USA sources, only from BOM, so the USA SSHS index is non-applicable and the -5 (unknown) value makes sense. Going back to data from 2021, it doesn't look like there was USA data for this storm then either, so the -1 value was likely a bug that has been since fixed.

Thanks,

Jennifer
