The archived weather data for the current month will be made available between 2:00am - 2:15am (local time) on the first day of the following month.

Notes

This data may be used free of charge, provided the Department of Physics at the University of Otago is acknowledged as the source of the data in any publically available material that utilises it.
 

Be aware there are gaps in earlier data sets:

1. Temperature, RH and solar (global and UV) sensors were removed for calibration from 2019-11-06 to 2020-09-21. The data from during this time is unreliable.
2. Faulty hardware has corrupted data from 2016-02-01 to 2016-02-02. It is indicated by zero global illumination in the daylight hours.
3. For approximately three weeks in February 2002 where there was a technical problem with the temperature, RH and solar sensors, and also UV data does not start until late January 2002.
4. Due to a clock adjustment problems, there are occasional cases of missing or duplicated time stamps on lines of data in files prior to September 2002.
5. Data recorded between 2023-07-31 14:35 and 2023-07-31 17:35 is unreliable due to the sensors being migrated to a new datalogger. Data for the UV-A and UV-B came back later at 2023-08-02 07:40.
