Subject:	SGP/EBBR/E18 - Water in Net Radiometer; Surface Fluxes are Incorrect
DataStreams:	sgp5ebbrE18.a1, sgp15ebbrE18.a1, sgp15ebbrE18.b1, sgp30ebbrE18.a1, sgp30ebbrE18.b1
Description:	The net radiometer top dome was punctured by migrating birds. This alone does not cause incorrect net radiation measurements. However, when it subsequently rains, water collects in the bottom dome, causing the net radiation measurements to be too large during the day and too small at night.

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).
Measurements:	sgp30ebbrE18.b1: latent heat flux(e) corrected sensible heat flux(h) average surface soil heat flow at the surface(ave_shf)

DataStreams:	sgp5ebbrE18.b1, sgp15ebbrE18.b1, sgp30ebbrE18.b1
Description:	The net radiometer dome was cracked and water had gotten in, resulting in incorrect net radiation measurements and therefore incorrect sensible and latent heat flux measurements.
Measurements:	sgp5ebbrE18.b1: specific humidity(q) sgp30ebbrE18.b1: latent heat flux(e) specific humidity(q) corrected sensible heat flux(h) sgp15ebbrE18.b1: Net radiation(mv_q)
