Subject:
MAO/PASS/S1 - Instrument problem
DataStreams:maoaospass3wS1.a1
Description:
Incorrect/Suspect Data due to noise
Noise was present at the start of the deployment due to unrecoverable issues occurring 
during shipment. Period 1 (P1) is for this period until when the instrument was removed for 
repair.  P2 is the period when the spare PASS was installed. P3 is the period of spare 
PASS data after a repair was attempted in the field.  P4 is when the original PASS was 
reinstalled after repair at the manufacturer.
Suggestions: 
All flagged data should be used with extreme caution.  Intercomparisons with other 

measurements are strongly suggested.  Data is noisy data with low signals due to internal 
issues with laser optics/stability.
