Description:	The AEM stopped before reaching the end of it's travel, causing the home signals to be between 0 and 3 during much of this period (therefore the data is colored yellow). All gradient data, sensible heat flux, latent heat flux, and the Bowen ratio are incorrect during this condition.

Description:	The AEM home30 signal is offset by approximately 25; it appears that the electronics of the AEM is adding the home15 and home30 voltages together when the AEM is in the home30 position.

The AEM home30 signal is offset by approximately 25 during part of this period; it appears that the electronics of the AEM is adding the home15 and home30 voltages together when the AEM is in the home30 position.

Description:	This condition occurred most of the time during the indicated period (hence color yellow). The left air temperature was incorrect only when the AEM was in the home 30 position. This only affected the bottom air temperature calculation. However, it made the latent heat flux, sensible heat flux, and Bowen ratio incorrect. The sensor was improperly inserted into the aspirator shield and was pinched between the shield and the T/RH probe. When the AEM was in the home30 position, the aspirator hose position may have caused the sensor to short to ground.

DataStreams:	sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1
Description:	Soil Temperature #4 was often incorrect, typically too large negative, during this period, causing other measurements calculated with it to be incorrect also. This was caused by a bad multiplexor channel, which was discovered by the vendor during recalibration of the unit later.

Description:	During much of the indicated period the Left T/RH Temperature was incorrect. Because the home signal was between 0 and 3, the temperature was incorrect when the AEM was at the bottom position, but was correct when the AEM was at the top position. This was caused by a short created when the sensor was mispositioned in the aspirator housing and enough strain on the cable for it to bring it into contact with the housing in the bottom position.

In all cases, temperature and humidity gradients were incorrect; thus the Bowen ratio, sensible heat flux, and latent heat flux are incorrect for the indicated periods. Even when the home 15 and 30 signals were different (but too high) the measurements were incorrect because the program keys off of the home signals, which must be in the proper ranges.

Subject:	SGP/EBBR/E13 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE13.b1
Description:	Effective 20050331.2100, the EBBR.E13 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 20050331, 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 sgp30ebbrE13.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE13.a1).
