Subject:	NSA/METTWR/C1 - C1 WIND SPEED DATA QUESTIONABLE
DataStreams:	nsamettwrC1.a1, nsamettwrC1.b1
Description:	The anemometers located at all 4 levels (2m, 10m, 20m, and 40m) are heated anemometers. The thermistors controlling the amount of power applied to the cups of the anemometers failed. This caused too much power to be sent to the heating elements. The cups bubbled and, in some cases, completely melted through.

Description:	From 020606.0150-0204, the met twr data (all levels) are all -9999 due to a power failure. The collection program was shut down from 0205-1930, so no data were collected. And from 1931-020607.1707, the data are all -9999 again due to the power failure.

Subject:	NSA/METTWR/C1 - C1/METTWR PRESSURE DATA MISSING AND INCORRECT
DataStreams:	nsamettwrC1.a1, nsamettwrC1.b1
Description:	Starting at 0501 UTC on 05/21, pressure readings frequently are out of tolerance. The read timeout value had changed from 250 ms to 150 ms. Changed the read time out back to 250 ms. Unknown as to how read timeout values changed.
Measurements:	nsamettwrC1.a1: Atmospheric pressure(atmos_pressure) nsamettwrC1.b1: Atmospheric pressure(atmos_pressure)
