Subject:	NSA/C1 data loss due to cut fiber optic cable
DataStreams:	nsaorgC1.a1, nsapwsC1.a0, nsamettwrC1.a1
Description:	The fiber optic line connecting the MET TWR to the data collection facility was accidentally cut during snow removal. Data are unrecoverable.

Subject:	NSA/METTWR/C1 - Met Tower Data Incorrect During Calibrations/Changeouts
DataStreams:	nsamettwrC1.a1, nsamettwrC1.b1

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.
Measurements:	nsamettwrC1.a1: Minimum Wind Speed(wind_spd_min) wind_spd_sd Mean Wind Speed(wind_spd_mean) Vector-averaged Wind Speed(wind_spd_vec_avg) Maximum Wind Speed(wind_spd_max) nsamettwrC1.b1: Maximum Wind Speed(wind_spd_max) wind_spd_out_of_range_error Mean Wind Speed(wind_spd_mean) wind_spd_sd Minimum Wind Speed(wind_spd_min) Vector-averaged Wind Speed(wind_spd_vec_avg)

Subject:	NSA/METTWR/C1 - C1 WIND DIRECTION DATA SUSPECT
DataStreams:	nsamettwrC1.a1, nsamettwrC1.b1
Description:	The wind direction sensor at the 10m level and 20m level became frozen. The senor at the 10m level became frozen on July 25 2001. The date that the 20m level became frozen is unknown but occurred after the 10m level became frozen. Both sensors froze in such a way as to consistently report wind direction values out of the south.
Measurements:	nsamettwrC1.a1: wind_dir_sd win_spd_out_of_range_error Minimum Wind Direction(wind_dir_min) Maximum Wind Direction(wind_dir_max) Vector-averaged Wind Direction(wind_dir_vec_avg) win_dir_out_of_range_error nsamettwrC1.b1: wind_dir_out_of_range_error wind_dir_sd Vector-averaged Wind Direction(wind_dir_vec_avg) Maximum Wind Direction(wind_dir_max) Minimum Wind Direction(wind_dir_min)
