Subject:	SGP/EEBR/E2 - AEM Stopped In One Position
DataStreams:	sgp5ebbrE2.a1, sgp15ebbrE2.a1, sgp15ebbrE2.b1, sgp30ebbrE2.a1, sgp30ebbrE2.b1

Subject:	SGP/EBBR/E2 - Reprocess: E2 EBBR Soil Temperature #2 Incorrect
DataStreams:	sgp15ebbrE2.a1, sgp15ebbrE2.b1, sgp30ebbrE2.a1, sgp30ebbrE2.b1
Description:	Soil Temperature #2 was intermittently incorrect. The cause is unknown. The indicated measurements that are calculated using soil temperature are also incorrect. Soil moisture #2 (30 minute only) was also affected because version 6 of the EBBR datalogger program uses a multiplication of soil temperature and soil moisture as part of the adjustment of soil moisture for soil temperature. This was discovered to be a poor technique soon after it was implemented, but E2 will continue to use version 6 until a replacement EBBR unit is available. When soil temperature #2 is large negative, soil moisture #2 is often twice as large as it should be. EBBR unit changeout dates are listed on the EBBR instrument web page.

Subject:	SGP/EBBR/E2 - Reprocess: E2 EBBR Soil Temperature #2 Incorrect
DataStreams:	sgp15ebbrE2.a1, sgp15ebbrE2.b1, sgp30ebbrE2.a1, sgp30ebbrE2.b1
Description:	Soil Temperature #2 was intermittently incorrect. The cause is unknown. The indicated measurements that are calculated using soil temperature are also incorrect. Soil moisture #2 (30 minute only) was also affected because version 6 of the EBBR datalogger program uses a multiplication of soil temperature and soil moisture as part of the adjustment of soil moisture for soil temperature. This was discovered to be a poor technique soon after it was implemented, but E2 will continue to use version 6 until a replacement EBBR unit is available. When soil temperature #2 is large negative, soil moisture #2 is often twice as large as it should be. EBBR unit changeout dates are listed on the EBBR instrument web page.

DataStreams:	sgpvceil25kB1.00, sgpvceil25kB1.a1, sgpvceil25kB1.b1
Description:	Beginning on 07/06/2003, frequent short-term data gaps began occurring. The situation continued to worsen until the PC locked up entirely on 07/14/2003. After the computer was re-booted, the data gaps stopped and have not returned. The problem appears to be restricted entirely to the computer and does not involve the ceilometer itself. Thus, there appears to be no problem with the data records that were properly collected.

DataStreams:	sgp5ebbrE2.b1, sgp15ebbrE2.b1, sgp30ebbrE2.b1
Description:	The upper dome of the net radiometer was broken. Normally this alone does not affect the net radiation measurement. However, in this case the breakage must have been more than just a bird claw hole or a crack, resulting in obstruction of the top sensing surface of the net radiometer and greatly reduced net radiation measurements. Sensible and latent heat fluxes were reduced as a result.

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).
