Instrument change a ~decade ago –
amazing nobody at GHCN has noticed this complete failure to calibrate the new instrument with what it replaced – data from KNMI Climate Explorer. Minimum affected too. This has historic significance because Hokitika was one of the “rural” series in Jones original global dataset in the 1980’s that had a ~century of data. Ruined for good now. I think the NZ Metservice runs the stations.
