Cumulus processes rainfall in one of two [[cumulus.ini| units]] (millimetres and inches). Most processing by Cumulus is based on the total rainfall count output by a weather station, see [[FAQ#My_station_invented_some_rain_that_didn.27t_really_occur.2C_and_I_want_to_set_it_to_zero_.28or_some_other_figure.29 | FAQ]] for more. The rainfall observations output by different weather stations varies, see [[Monthly_log_files]] for the parameters that Cumulus tracks. Cumulus can also read rainfall from a separate RG11 optical gauge. | Cumulus processes rainfall in one of two [[cumulus.ini| units]] (millimetres and inches).

== Rain day == | |||
On the Cumulus '''View''' | The threshold value which the daily rainfall has to equal or exceed for the day to be considered a 'rain day' is set in [[Cumulus.ini#Section:_Station | RainDayThreshold]] and has a default value of ''-1'' that means 0.2mm or 0.01in. Alternative thresholds can be used by specifying a number in the units your configuration uses. | ||
* | == Cumulus View Menu == | ||
=== Highs and Lows === | |||
On the Cumulus '''View''' ''Highs and lows'' screens you can see those of the following appropriate to the chosen period: | |||
* Highest Hourly/Daily/Monthly Rainfall | |||
* High rain rate | * High rain rate | ||
* Longest wet period (count of consecutive days with rainfall above configured threshold) | |||
* Longest dry period (count of consecutive days with rainfall below configured threshold) | |||
These screens display the Highest or Longest extreme values for various rainfall categories; the same values are available from [[Webtags]]. | |||
=== ''This month/period/year'' screens === | |||
A number of values are shown for rainfall (all include start day, but exclude end day of period selected): | |||
* Total for this (any) month | |||
* Total for this (any) period you want (select start date included and end date excluded) | |||
* Total for this (any calendar) year is shown on 'This year' screen | |||
* Wettest day (equivalent to 'Highest Daily Rainfall' parameters of webtags) | |||
* High rainfall rate | |||
* Rain days (count of days with rainfall above configured threshold) | * Rain days (count of days with rainfall above configured threshold) | ||
* Dry days (count of days with rainfall below configured threshold) | * Dry days (count of days with rainfall below configured threshold) | ||
