Description:	The upper dome of the net radiometer was broken. Normally this alone does not affect the net radiation measurement.

Subject:	SGP/EBBR/E2 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE2.b1
Description:	Effective 20050324.1700, the EBBR.E2 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 20050324, 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 sgp30ebbrE2.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE2.a1).

DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	The top dome of the net radiometer was broken and water entered, causing incorrect net radiation measurements. This resulted in incorrect sensible and latent heat fluxes.

Subject:	SGP/EBBR/E2 - Average Soil Heat Flux Incorrect
DataStreams:	sgp30ebbrE2.b1
Description:	A typo in the version 9 EBBR program caused average soil heat flow to be zero, resulting in both sensible and latent heat fluxes being approximately 20 watts per meter squared too large during the middle of the day.

Subject:	SGP/EBBR/E2 - metadata corrections
DataStreams:	sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E2 data collected by ARM back to the installation of the instrument in May 1997. 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:	sgp5ebbrE2.b1: base time(base_time) sgp30ebbrE2.b1: base time(base_time) sgp15ebbrE2.b1: base time(base_time)
