Subject:	SGP/THWAPS/B4 - Temp and RH values incorrect during hours of no sunlight
DataStreams:	sgpthwapsB4.b1
Description:	Unknown issues caused the temp and RH values to become lower during non-sunlight hours. The affects are best seen at sunrise and sunset when the data would adjust upward or downward abruptly. Plots of the standard deviation show abrupt spikes at these times. Comparison plots to nearby mesonet sites suggest the nighttime values of both temp and RH are lower than nearby sites. This problem was also very intermittent and was not occurring on a daily basis. A complete move of the sensors and collection system to a separate building repaired the problem.

DataStreams:	sgp1440smosE27.b1, sgp1smosE27.b1, sgp30smosE27.b1
Description:	A recent ice storm caused the wind speed and wind direction values to flat line to zero. Both values came back on 1/29/09, but wind direction flat lined at 355 degrees. The wind direction values appear to recover on the 02/10/2009 but are still suspect. The wind sensor was replaced on 02/24/2009.
