Seven-station temperature data spreadsheet
The spreadsheet was updated to correct a historical data entry error for one location for a month in 1910.
A number of other changes were made in the climate database:
- digitising small amounts of data from early last century previously held in paper records in Wellington and Nelson
- creating two station numbers for Hokitika to reflect the fact there were two sites.
