BS_Temporal_

BS_Av_Time
is the backscatter average time in
seconds. 1 to 30 (default 5).
Note: Must not be greater than
Measurement_
Period
– 1.0
Noise_Gate
controls the noise threshold applied to
back-scatter.
Noise_Gate
= -1000, all backscatter range is
corrected.
Noise_Gate
= 0.0 to 1000.0, standard deviation
(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 8M is polled, it
will output the last measurement made. If between 2
and 600 seconds, the SkyVUE 8M 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 ). 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 30 s); 0
gives polled messages.
Note: Must be a multiple of
