6.15 Precipitation Type
Sampling rate Event-dependent on reaching the response threshold
Response threshold 0.002mm (Radar)
Response threshold 0.2 / 0.5 mm (Rain Gauge)
Follow-up time 2 minutes
Request channels:
Measurement Variable (uint8)
0 = No precipitation
60 = Liquid precipitation, e.g. rain
70 = Solid precipitation, e.g. snow
40 = unspecified precipitation
(WS401-UMB, WS601-UMB, external
rain gauge)
Note: A detected precipitation type remains valid for 2 minutes after the end of the
precipitation event. In order to record precipitation types which only occur for a short period
(e.g. short-term rain), the request interval should be 1 minute or shorter.
Ice, hail and sleet are transmitted as rain (60).
The versions WS401-UMB and WS601-UMB as well as the external rain gauge do not
include detection of precipitation type, so in this case only type 40 (unspecified precipitation)
is indicated. Due to the function of the rain gauge only liquid or molten precipitation can be
recognized.

6.17 Global Radiation
Sampling Rate 10 seconds
Generation of average values 1 – 10 minutes *)
Unit W/m²
Request Channels:
Measurement Variable (float32)
*) Until device version .49 / .212 / Firmware v5.6: 1400.0 W/m

*) Note: The average, maximum and minimum values are evaluated from the 1 minute
averages of the 10 second spot value.
When operated in Power Saving Mode 1 (see page 37) the WS700-UMB will measure the
global radiation only once per minute.
