NSA/METTWR/C1 - C1 WIND SPEED DATA QUESTIONABLE
DataStreams:nsamettwrC1.b1, nsamettwrC1.a1
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.

NSA/METTWR/C1 - C1 WIND DIRECTION DATA SUSPECT
DataStreams:nsamettwrC1.b1, nsamettwrC1.a1
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 - 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.

NSA/METTOWER - Questionable NSA Met-tower wind data
DataStreams:nsamettwrC1.a1, nsametC1.00
Description:
The data analysis software for the NSA Met_tower system was upgraded at 2200 GMT
on 8 SEP 1999.  The upgrade included replacement of missing data with -99.99's
when the routine that polled the Met-tower sensors timed out.  This 
resulted in large negative spikes in the 1-min averages.  These spikes 
almost always occurred during the first several 1-min periods of a 
half-hour data processing routine.
On 25 OCT 1999 at 2300 the routine that replaced missing data was changed to 
insert the previous 1-min averaged data instead of -99.99.  Since at the most
only one or two values are missing in ay averaging period, this change 
results in a reasonable estimate of the true mean values

NSA/METTOWER - Questionable NSA Met-tower wind data
DataStreams:nsamettwrC1.a1, nsametC1.00
Description:
The data analysis software for the NSA Met-tower system was upgraded at 2200 GMT
on 8 SEP 1999.  The upgrade included insertion of  -99.99's for the wind vectors 
when the wind speed or direction were either missing or equal to 0.  This 
resulted in incorrect vector averaged wind speed, wind direction, and 
standard deviation of wind direction.  When this occurred, the 
vector-averaged wind speed and standard deviation of wind direction 
were often abnormally high and the vector-averaged wind direction
 was often approximately 225 deg.  Starting at 2300 GMT on 25 OCT 99
missing wind data were replaced by the previous 1-min average and 
starting at 2200 GMT on 15 NOV 1999 the computed wind vectors were 
used whenever wind speeds or wind directions were 0.

From the time of installation of the NSA C1 Met-tower system on 24 MAR 1998
until 29 NOV 1999 all wind direction minima and maxima were reported as raw

be subtracted from the value.  All mean wind directions were computed from
rotated (corrected) data.
