NSA/METTWR/C1 - Tower Maintenance
DataStreams:nsamettwr4hC1.b1
Description:
The booms of the tower were lowered for sensor replacement, calibration, and tower 
maintenance.  During the maintenance and sensor replacement data are frequently missing.  Where 
data are available, they are not or may not be representative because the booms were at 
the base of the tower during the time period listed.

The chilled mirror measurements were not affected by the maintenance.
Suggestions: 
Do not use.
