SGP/MWR/C1 - Intermittent Negative Sky Brightness Temperatures

Several related and recurring problems with the SGP MWRs have been
reported dating back to 1999.  These problems were due to the
occurrence of blackbody signals (in counts) that were half of those
expected. The symptoms included noisy data (especially at Purcell),
spikes in the data (especially at Vici), negative brightness
temperatures, and apparent loss of serial communication between the
computer and the radiometer, which results in a self-termination of the
MWR program (especially at the CF).

Because these all initially appeared to be hardware-related problems,
the instrument mentor and SGP site operations personnel (1) repeatedly
cleaned and replaced the fiber optic comm. components, (2) swapped
radiometers, (3) sent radiometers back to Radiometrics for evaluation
(which has not revealed any instrument problems), and (4) reconfigured
the computer's operating system.  Despite several attempts to isolate
and correct it, the problem persisted.

It became apparent that some component of the Windows98 configuration
conflicted with the DOS-based MWR program or affected the serial port
or the contents of the serial port buffer. This problem was finally
corrected by upgrading the MWR software with a new Windows-compatible
program.

SGP/NWS/X1 - Six second soundings upgraded to one second soundings for Norman, OK

On November 13, 2006 the Norman, OK changed over to the Radiosonde Replacement System 
(RRS).  With the change to RRS there were some changes in the instrumentation and data 
processing:
1) The winds are now from a GPS.
2) The data are now at 1 second vertical resolution.
3) There is some additional information in the header records.
4) The smoothed and processed version of the data have been used. Corrections, such as the 
solar radiation correction, have been applied.

Notes.
