Be aware there are gaps in earlier data sets:
- 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.
- Faulty hardware has corrupted data from 2016-02-01 to 2016-02-02. It is indicated by zero global illumination in the daylight hours.
- 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.
- 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.
