In the current data table:
- Temperature: Temperature is recorded from the 2 sensors continuously during the 10 minute interval. The values of the 2 sensors are averaged and the lowest average is used as the current temperature. This seems to give reasonably accurate results from 2 sensors that are not ideally located.
- Dew point: The dew point of the air calculated from the humidity sensor and the current air temperature.
- Humidity: Measured every 10 minutes and displayed as a percentage. Dew point is calculated from this measurement.
- Wind Speed: The maximum gust recorded in the 10 minutes prior to the report time using 3 second samples.
- Wind avg. speed: The average wind speed in the 10 minutes prior to the report time using 3 second samples.
- Wind Direction: The direction that most of the wind has come from in the 10 minutes prior to the report time.
- Barometer: Measured continuously during the 10 minute interval. The average of these values is displayed as the current pressure in hPa.
- Rainfall: The total rain that has fallen in the past 10 minutes.
In the Today's Weather and Yesterdays table:
- Temperature: Temperature is measured every 10 minutes as above. The Maximum and Minimum temperatures recorded since midnight. The average (mean) temperature for the day calculated from the data collected since midnight
- Humidity: The maximum and minimum humidity recorded for the day.
- Wind speed: is sampled every 3 seconds and the max and average speed are calculated every 10 minutes from these 3 second samples. All the data displayed is based on these 10 minute records.
- Wind Direction: is sampled every 3 seconds. The direction with the highest count is the prevailing direction. Every 10 minutes this data is added to the 10 minute record.
- Maximum Gust: is the maximum wind speed in a 10 minute record since midnight.
- Average Speed: is the average wind speed since midnight calculated from the 10 minute records.
- Wind Run: is the total distance that wind has traveled past the anemometer since midnight calculated from the 10 minute records.
- Prevailing Wind Direction: is the direction with the highest count since midnight calculated from the 10 minute records.
- Barometer: The maximum and minimum recorded for the day along with the pressure change, the difference between maximum and minimum. The current pressure is compared to that measured 60 minutes ago and the trend is displayed as Falling, Rising or Steady. If the change is greater than 0.3hPa, Falling or Rising is displayed, else the barometer is Steady for the past hour.
- Rainfall: Rainfall data is collected every 10 minutes. Max 10 Minute Total is the greatest amount of rain recorded in 10 minutes since midnight. Total Rainfall is the rainfall collected since midnight.
