The result of these errors is that some significant errors with magnitudes up to twice the cyclone translation speed have been introduced into some of the storm relative wind speeds that are contained in the Level 3 data product (L3). If you are not using the storm-relative wind speeds of the L3 data products, you should not be affected by this issue. The earth-relative wind speed parameters are unaffected. I plan to regenerate the L3 data product for all cyclones in the dataset in the near future and will notify this list when the revised dataset files are ready. I also plan some additional enhancements to the metadata of the good radial legs. Best regards, Jonathan Vigh
