|-
| AirQualityDecimals=1
| Release 3.9.2
| Units → Advanced Options (Here be dragons!)
| Air Quality decimals
| 1  (displayed as blank)
| Number of decimal places for all outputs
|-
| AvgBearingMinutes=10
| Legacy Cumulus
| Common Options → Advanced Options (Here be dragons!)
| 10 (minutes)
| This parameter's value is the number of minutes over which Cumulus calculates (by treating the wind as a vector and taking into account the speed as well as direction) its average bearing
|-
| AvgSpeedMinutes=10
| Legacy Cumulus
| Common Options → Advanced Options (Here be dragons!)
| 10 (minutes)
| This parameter's value is the number of minutes over which Cumulus averages out reported current wind speeds
|-
| ChillHourSeasonStart=
| Legacy Cumulus
| (TO BE DETERMINED)
| Default depends on release
* (up to 3.11.4) 10 = October
* (from 3.12.0) 4 in Southern hemisphere, 10 in Northern hemisphere
| The value to enter is the month number (1=January, 12=December) and the Cumulative Chill Hours Count is reset to zero on the first of the selected month
|-
| ChillHourThreshold=
| Legacy Cumulus
| (TO BE DETERMINED)
| Default depends on Temperature Units
* Either 45 degrees Fahrenheit (equivalent to 7.22 <sup>o</sup>Celsius)
* Or 7 degrees Celsius (equivalent to 44.6 <sup>o</sup>Fahrenheit)
| Chill Hours are incremented by the number of (fractional) hours that the air temperature is below the threshold. In practice, Cumulus simply detects if the current temperature is below the threshold and adds an increment equivalent to the (interval) time passed since the last temperature reading.
* You can put in any value you want, with a decimal place if required
* Some people have put in the freezing-point temperature (0<sup>o</sup>C or 32 <sup>o</sup>F) and they relabel "chill hours" to "frost hours"
|-
| CloudBaseInFeet=0
| Legacy Cumulus
| (As at 3.11.4, can only adjust in the file)

* 0 = don't log (default if file created by legacy software)
|-

| n/a
| (TO BE DETERMINED)
| For derivatives like count of consectuative wet/dry days, any daily rainfall less than this threshold will be ignored.
(If rainfall is measured in tips, usually set to just over one tip, as first tip of day might be result of less that one tip accumulated on earlier days or because of dew)
|-
| RainDecimals=1
| Release 3.9.2
| Units &rarr; Advanced Options (Here be dragons!)

* Don't tick (value shown as 0 in Cumulus.ini) then effect depends on whether your weather station supplies pressure trends
** If your station does supply pressure trends, then MX will use those
** If your station does not supply pressure trends, then MX will generate the name for the current pressure trend, e.g. "Falling", "Rising quickly" etc, instead of the one supplied by your station. The names used are those in the UK Shipping Forecast, but can be modified using [[strings.ini]].
