Subject:	SGP/SWATS/E18 - Physical changes to reinstallation
DataStreams:	sgpswatsE18.00, sgpswatsE18.b1
Description:	Due to the unique occurrence of a reinstallation of sensors at an existing SWATS facility, there are several differences between the existing sensor profiles at Morris and the rest of the SGP SWATS profiles. The two profiles are north/south of each other rather than east/west. Also, the horizontal separation of the profiles is 0.5 meters rather than 1.0. Sensors below the 60-cm depth were not reinstalled in an effort to avoid the susceptibility to lightning damage which was probably enhanced by the water table below 60 cm. The north/south alignment and 0.5-meter separation do not affect the significance of the data with regard to surface flux or hydrological modeling. Users should simply be aware that the sensors are configured slightly differently from the other SWATS facilities.

Subject:	SGP/VCEIL/B5 - Noisy Backscatter
DataStreams:	sgpvceil25kB5.b1
Description:	Since October of 2004, the noise in the backscatter plots occasionally become high in amplitude for periods of time lasting anywhere from an hour or so to as much as a day. This problem appears similar to a dirty window (such as the problem at B6 last week), but the fact that the plots show high amplitude for short durations of time imply that this problem is different. Cloud base height detection appears to be unaffected.

Subject:	SGP/EBBR/E18 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE18.b1
Description:	Effective 20050330.0000, the EBBR.E18 CR10 program was revised to improve the quality of the primary measurements as follows: 1) An RMS procedure is used to determine max and min limits of acceptable soil heat flow. This is applied to the individual soil sets. Measurements outside the limits are rejected and the measurements within the limits are used to calculate the average soil heat flow. 2) Max and min limits are used to determine incorrect values of net radiation, sensible heat flux (h), latent heat flux (e), and automatic exchange mechanism (AEM) signal. If AEM signal is outside the limits, h and e are set to 999s. If net radiation is outside the limits, h and e are set to 999s. If h or e are outside the limits, h and e are set to 999s. Virtually no incorrect soil measurement will affect the primary measurements of h and e. By setting h and e to 999s, it can be easily seen that the primary variables are incorrect; no other interpretation is possible. Prior to 20050330, the improved CR10 program was NOT in effect. DQRs have been submitted for known instances of incorrect soil measurements which affected the quality of the primary measurements of h and e. Note: the DQR begin date is the begin date of the sgp30ebbrE18.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE18.a1).

Subject:	SGP/THWAPS/B5 - Minor biases in humidity and saturation vapor pressure
DataStreams:	sgpthwapsB5.b1
Description:	The THWAPS humidity sensor output was scaled so that the instrument output voltage range (0-1VDC) represented 0-100 %RH. Comparisons with the co-located chilled mirror sensor at the CF suggested that the THWAPS RH sensor was reading artifically low at high humidities because of this 100 %RH maximum. The scaling of the system was changed so that 0-1 VDC now represents 0-110 %RH. This resulted in a slight loss of precision in the measurements, but since the RH measurement is only accurate to 2-3 %RH at best, this isn't a significant problem. The saturation vapor correction when temps are below 0C contained an error in the multiplier. The incorrect multiplier only equates to an error of 0.01 kPa which is less than the stated uncertainty of the measurement (+/- 0.035 kPa).
