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.

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.

DataStreams:	nsametC1.b1, nsatwrC1.b1
Description:	The new t/rh probe installed during annual calibrations and checks began to exhibit readings that were biased high compared to the Chilled Mirror Hygrometer. In high RH conditions the sensor would consistently report RH values in excess of 105%. Comparisons to the other tower levels also suggested that the 2m level RH data is suspect.

Subject:	NSA/METTOWER - Questionable NSA Met-tower wind data
DataStreams:	nsametC1.00, nsamettwrC1.a1
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

Subject:	NSA/METTOWER - Questionable NSA Met-tower wind data
DataStreams:	nsametC1.00, nsamettwrC1.a1
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.
