Subject:	SGP/EBBR/E20 - Reprocess: Soil Temperature #3 Incorrect
DataStreams:	sgp30ebbrE20.a1, sgp30ebbrE20.b1
Description:	Soil temperature 3 was incorrect during the indicated periods. 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 + g2 + g4 + g5)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf)
Measurements:	sgp30ebbrE20.b1: 0-5 cm change in soil heat storage with time, site 3(ces3) 0-5 cm integrated soil temperature, site 3(ts3) average surface soil heat flow(ave_shf) latent heat flux(e) soil heat flow, site 3(g3) h(h) sgp30ebbrE20.a1: latent heat flux(e) soil heat flow, site 3(g3) 0-5 cm change in soil heat storage with time, site 3(ces3) h(h) average surface soil heat flow(ave_shf) 0-5 cm integrated soil temperature, site 3(ts3)

Subject:	SGP/EBBR/E20 - Soil Moisture #4 and Soil Temperature #4 Incorrect
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1
Description:	Failures of a multiplexer channel and a J-panel channel caused soil temperature #4 and soil moisture #4 to spike and drift at times. Replacement of the failed equipment solved the problem.

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).
Measurements:	sgp30ebbrE20.b1: average surface soil heat flow(ave_shf) latent heat flux(e) h(h)

Subject:	SGP/EBBR/E20 - metadata corrections
DataStreams:	sgp15ebbrE20.b1, sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E20 data collected by ARM back to the installation of the instrument in April 1993. Please see the current metadata for correct information. These changes do not affect data values or quality. The changes are summarized below: 1) Update of "sensor location" information 2) Addition of installation dates for the systems 3) Correction of soil moisture units (from "by volume" to "gravimetric")
Measurements:	sgp30ebbrE20.b1: base time(base_time) sgp15ebbrE20.b1: base time(base_time) sgp5ebbrE20.b1: base time(base_time)
