Calculations
Statistical calculations such as minimum, maximum, averages,
standard deviation, and cumulative values, are calculated over user set
periods at user set intervals independently for each measured and
calculated parameter.
An Example of the Calculations Setup Window
The extreme values can have time stamps accurate to seconds
(selectable format hh:mm:ss).
A library of ready made calculations is available in the MAWS
software, including, for example, unit conversions, dew point, QNH,
QFF, QFE, evapotranspiration, wind chill, heat stress and frost point,
MacArthur fire index, rain duration (requires DRD11A sensor) etc. In
addition, the sunshine duration can be calculated using the data from
the global solar radiation sensor. The CM6B or CM11 global solar
radiation sensor is recommended for this purpose.
