The resolution and accuracy of the various components, as displayed on this web site are as follows:
| Resolution | Accuracy ± | |
| Barometric pressure | 0.1 hPa | 1.0 hPa |
| Temperature | 0.1ºC | 0.5ºC |
| Humidity | 1% | 3% |
| Wind direction | 1º | 4º |
| Wind speed | 0.1 m/s | 5% |
| Precipitation | 0.2 mm | 4% |
| Rainfall rate | 0.1 mm/h | 5% |
Note that the accuracy figures are extreme limits and it is expected that the figures will generally be more accurate under conditions in the middle of the range of each variable, i.e., under normal weather conditions.
The station is fitted with a Davis WeatherLink datalogger, which records all the weather data at 1 minute intervals, even when the computer is not operational.
