→What do the various wind speeds in Cumulus correspond to, with Fine Offset stations?
|
Fine Offset sensors measure wind over 48-second intervals, divided into 24 2-second intervals. At the end of each 48-second period, they transmit the highest of those 24 values as 'Gust', and the average of those 24 values as 'Wind'. The console keeps writing the newly received Gust and wind values to the same area of console memory every 48 seconds, until the station logging interval time is reached, then it moves on to the next memory location, leaving the last values it wrote in the previous console memory location.
*If Cumulus is not running all the time, on restart it works through the console memory locations and extracts the Fine Offset Wind and Gust in each memory location, i.e. at the station logging interval.
*While Cumulus is running, it reads the current wind speeds (and direction) every 10 seconds.
Cumulus, for various reasons, uses different terminology, and also has configuration settings which control how some of the wind values are displayed.
