Description
(default 2) for noise threshold. Only backscatter above
this is range corrected.
Measurement_Period
= 0 or 2 to 600 seconds
(default 10). If set to 0 and the SkyVUE 8 is polled, it
will output the last measurement made. If between 2
and 600 seconds, the SkyVUE 8 continually outputs
messages. For sky condition output, Campbell
Scientific recommends setting the
measurement_
Period
≤ 30 seconds. If a
measurement_Period
is greater than 30 seconds, the sky condition algorithm
will be less able to resolve coverage for higher layers.
Note: Must be a sub multiple of
Message_
Interval
Rolling_Average
= 1 to 29 (default 3). This is the
number of measurement_periods to use in a
rolling average of the backscatter.
Message_Interval
is the message interval in
seconds. Range is 2 to 600 seconds (default 10 s); 0
gives polled messages.
Note: Must be a multiple of
Measurement_
Period
BS_Temporal_ Filter_Mode
allows the
selection of backscatter filtering modes.
0 = Averaging
1 = Median signal processing
Default setting is 1, the median mode for aviation.
CLOSE
No parameters Closes the terminal interface to allow normal message
output and saves new settings to flash non-volatile
storage.
CLOUDMODE CloudMode_A
CloudMode_A
turns on a filter that reports the
highest cloud during precipitation to avoid
