HighResMIP-PRIMAVERA tropical cyclone tracks derived from Atmospheric Reanalysis datasets

These tropical cyclone tracks were created as part of the HighResMIP-PRIMAVERA projects. They were generated from 6 hourly Atmospheric Reanalysis data, and used the TempestExtremes (Ullrich and Zarzycki 2017; Zarzycki and Ullrich 2017) code for detection and stitching. The exact commands used are part of the file metadata.

They are companion to the CMIP6 HighResMIP model tropical cyclone tracks published at CEDA: http://catalogue.ceda.ac.uk/uuid/e82a62d926d7448696a2b60c1925f811

They were created around 2018, so the datasets end around 2017/2018.

The reanalyses dataset used (data having been downloaded in ~2018, so any changes to the data or TempesetExtremes since then will not be reflected in the tracked data) were:
