DataStreams:	sgp30ebbrE20.a1, sgp30ebbrE20.b1
Description:	Soil heat flow #3 measurements were incorrect during it's replacement. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g5)/2 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) Note: during the time period referenced here, soil heat flow #4 and #2 were also incorrect. This quality information is documented in D020717.46, D020717.47 and D020726.1.

DataStreams:	sgp30ebbrE20.a1, sgp30ebbrE20.b1
Description:	Soil heat flow #2 measurements had a negative offset. Negative values were too small and negative values occurred when positive values should have. This can occur when there is a poor wire connection or a J-panel over-voltage protection device has failed. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g3 + g4 + g5)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf)

Subject:	SGP/EBBR/E20 - Reprocess: Soil Heat Flow #2 and #4 incorrect
DataStreams:	sgp30ebbrE20.a1, sgp30ebbrE20.b1
Description:	Soil heat flow #2 measurements had a negative offset. Negative values were too small and negative values occurred when positive values should have. This can occur when there is a poor wire connection or a J-panel over-voltage protection device has failed. Soil heat flow #4 was incorrect because it's wires were loose from the connection terminals. Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g3 + g5)/3 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf)

DataStreams:	sgp30ebbrE20.a1, sgp30ebbrE20.b1
Description:	For the half hour data after CR10 datalogger startup, stored soil temperature values do not exist from the beginning of the half hour. Therefore soil heat storage can not be calculated correctly. This affects numerous measurements that are calculated using soil heat storage.

Subject:	SGP/EBBR/E20 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE20.b1
Description:	Effective 20050330.1900, the EBBR.E20 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 sgp30ebbrE20.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE20.a1).
