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.

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.

NSA/METTWR/C1 - Wind Speed data intermittently bad
DataStreams:nsamettwrC1.a1, nsamettwrC1.b1
Description:
Wind speed at 20m level icing up and wind speed values are intermittently
0 m/s, lower than other sensors and good at times.  Heater failure on sensor
that prevents icing.

  • Minimum Wind Speed(wind_spd_min)
  • Maximum Wind Speed(wind_spd_max)
  • Vector-averaged Wind Speed(wind_spd_vec_avg)

NSA/METTWR/C1 - Data missing due to Power Failure
DataStreams:nsamettwrC1.a1, nsamettwrC1.b1
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.
