In order to wrap up the HadISD dataset nicely, I decided that doing an official final version could be useful. So that it has the largest possible number of stations, I also re-selected stations for this release, hence the extra increase in version number. There are 10405 stations in this final version of the HadISD - v3.4.3.2025f.

Usually I would redo the station selection in February of a calendar year, having done the final release of a previous version and the associated homogeneity assessment in early January. However as I'm not expecting any further updates to the ISD, it made sense to roll this all into one. Hence, I have also run the homogeneity assessment for version v3.4.3.2025f.
In due course these this dataset will be archived on the CEDA Archive.
This dataset has been part of my work for the last 15 years, and although sad to see it finish, I'm also excited to see what the future will bring with GHCNh/C3S In Situ Observations.
