NSA/TWR/C1 - 40m and 20m Data Incorrect
DataStreams:nsatwrC1.b1
Description:
A power distribution problem required us to shut down power to the 40m level.  All T/RH 
were missing and the 40m wind sensor did not have heat to remove any ice build up.  All 
wind data from the 40m level should be viewed critically before use.  The 20m T/RH sensor 
was power spike when the problem occurred causing this sensor to become erratic.  
See D100302.2 for the continuation of the 40m problem.
