Snowfall is detected if Snowfall, precipitation limit is exceeded and the tem-
perature is below Snowfall, max. temperature . To suppress this status set Snow-
fall, precipitation limit to ≤0 .
A snow cover emerges if Snow settling, strength drop is exceeded and Snow set-
tling, maximum level is not reached. To suppress this status set Snow settling,
maximum level to a negative value.

Unit Description
05 Precipitation - Dimensionless value representing precipitation type and
intensity. Its range is 0 to 1000, where 1000 is the most
intensive precipitation that can be expected. The value
strongly depends on the type of precipitation: wet snow
that falls in large flakes gives high values, cold, small flakes
give lower values even though snowfall can be intense. Rain
generally gives lower values than snow.
The precipitation value is used to optimize the rate of
change filter (RoC) that is affected by reflections of pre-
cipitation. It cannot substitute a rain gauge.
