Subject:
NSA/SKYRAD/C1 - Noisy PIR data at Barrow
DataStreams:nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
Description:
PIR1 data is noisy throughout the entire period, though there is still a definite signal 
through the noise.
Suggestions: 
Averaging of the PIR1 data may reduce the noise somewhat while still maintaining the 

signal in the data. There is a second shaded PIR instrument that also measures shaded 
downwelling longwave radiation at the site.
