Subject:	SGP/EBBR/E12 - Reprocess: Soil Temperature #3 Incorrect
DataStreams:	sgp30ebbrE12.a1, sgp30ebbrE12.b1
Description:	Soil Temperature #3 was flaky primarily during nighttime hours and sometimes during early daylight hours. Average soil heat flow, sensible heat flux, and latent heat flux are also affected; these can be recalculated using the remaining good sets of soil sensors as follows: The heat fluxes can be recalculated by using soil sets 1, 2, 4, and 5 as follows: ave_shf = (g1 + g2 + g4 + g5)/4 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf)

Subject:	SGP/EBBR/E12 - Reprocess: Soil Moisture 4 and 5 Incorrect
DataStreams:	sgp30ebbrE12.a1, sgp30ebbrE12.b1
Description:	Soil moisture measurements from sets 4 and 5 were incorrect, leading to many other incorrect measurements calculated using them. Average soil heat flow, sensible heat flux, and latent heat flux are affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g2 + g3)/3 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) Note: D020717.6 reports Soil temperature sensor #3 was also bad during this time, but for the very specific records affected by the soil moisture #4 and #5 reporting incorrectly, soil temp #3 was okay. Therefore the equations given are correct.

DataStreams:	sgp30ebbrE12.a1, sgp30ebbrE12.b1
Description:	Soil moisture measurements from sets 2 and 5 were incorrect, leading to many other incorrect measurements calculated using them. Average soil heat flow, sensible heat flux, and latent heat flux are affected; these can be recalculated using the remaining good sets of soil sensors as follows: ave_shf = (g1 + g3 + g4)/3 e = -(q + ave_shf)/(1 + bowen) h = -(q + e + ave_shf) Note: D020717.6 reports Soil temperature sensor #3 was also bad during this time, but for the very specific records affected by the soil moisture #2 and #5 reporting incorrectly, soil temp #3 was okay. Therefore the equations given are correct.

Description:	The net radiometer top dome was punctured by migrating birds. This alone does not cause incorrect net radiation measurements.

Subject:	SGP/EBBR/E12 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE12.b1
Description:	Effective 20050329.1830, the EBBR.E12 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 20050329, 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 sgp30ebbrE12.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE12.a1).

Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E12 data collected by ARM back to the installation of the instrument in August 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 type 4) Correction of soil moisture units (from "by volume" to "gravimetric")
