NSA/SONDE/C1 - Broken temperature sensor

It appears that the temperature sensor on this radiosonde broke after launch.  There is a 
sudden drop of 12 degC in 2 seconds and the remaining tdry values seem to be about 30 
degC low.

NSA/SONDE/C1 - This is a test sounding done using an RS80H radiosonde

This was a sounding done using an RS80H radiosonde to test a special operational 
procedure.  There is nothing wrong with the data, though users should be aware that the sounding 
was not done using the current ARM standard RS90 radiosonde.

NSA/SONDE/C1 - Test sounding using RS80H

This is a test sounding done using an old RS80H radiosonde rather than the production RS90 
version.  Although the sonde functioned normally, the RH data may be subject to a dry 
bias caused by the age of the sensor and possible contamination.

NSA/SONDE/C1 - Incorrect surface altitude

The value of the station altitude (relative to mean sea level) is
incorrect in all NSA radiosonde files prior to 2/14/2004.  The correct
value is 8 m.  The incorrect value can be different.  Prior to 4/24/2002
(in platform nsaisssonde...) it was given as 12 m.  From 4/24/2002 to
2/13/2004 (in platform nsasondewnpn...) it is almost always given as
27 m (sometimes [rarely] 17 m).

NSA/SONDE/C1 - Bad temperature

Because of strong winds, the radiosonde hit the ground after launch and the temperature 
sensor broke.  The RH and pressure data also should be considered suspect.
