Description:	The home30 measurements sometimes exceeded 34.9999, resulting in the qc flag being set. However, this does not create any data quality issues. The qc flag is set just to provide an alert that the automatic exchange mechanism may have a problem; in this case data was not affected. An electronics repair solved the problem.

Subject:	SGP/EBBR/E22 - AEM Home Signals Too High
DataStreams:	sgp30ebbrE22.a1, sgp30ebbrE22.b1, sgp5ebbrE22.a1
Description:	The AEM home signals were too large at times during the indicated period; it has been determined by the vendor that this is usually caused by electrical noise in the vicinity. When the 30 minute data shows a home 30 signal of 35 or more, the bowen ratio, and sensible and latent heat flux measurements are incorrect Removing the jumper between 4L and AG on the CR10 and adding a jumper to Multiplexer 2, Set 6, between L1 and L2 fixed the problem. The vendor intends to make this modification to all EBBR systems as they return for re-calibration.

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

Subject:	SGP/EBBR/E22 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE22.b1
Description:	Effective 20050330.1930, 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).

Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E22 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 type 4) Correction of soil moisture units (from "by volume" to "gravimetric")
