Description:	The EBBR net radiometer at E15 was suspected to be off of level because the daily peak net radiation was recorded later than it was recorded by the SIRS. Site Ops found the EBBR net radiometer at E15 was significantly off of level (1/2 bubble tipped to the north). Adjustment of the level improved the comparison of peak time with the co-located SIRS.

Subject:	SGP/EBBR/E15 - Soil Moisture Coefficients Incorrect
DataStreams:	sgp30ebbrE15.b1
Description:	The soil Moisture coefficients used for E15 were incorrect from the time of installation of the system in program version 8. On 9 July 02 parameter 4 (an offset value) of program step 136 was changed from 9.5264 to the correct value 0.95264 (this error had been made by the vendor). The error masked the real problem (wrong soil type) and after 9 July 02 resulted in very low soil moisture measurements. The coefficients used were for coarse sand. On 28 Sep 04 I visited the E15 site and found the soil type a fine sandy clay or fine sandy loam. I changed the coefficients at 1509 GMT to those for a very fine sandy loam; this produced reasonable soil moistures for the soil type. The old coefficients in parameters 4 through 9 for step 136 of the program were: 0.95264, -6.7859, 36.224, -58.619, 25.073, 4.2278 The new coefficients are: 10.241, -27.943, 49.523, -12.648, -52.643, 38.054

Subject:	SGP/EBBR/E15 - Soil Heat Flows Undermeasured, and Latent and Sensible Heat Fluxes Overstimated
DataStreams:	sgp30ebbrE15.b1
Description:	Use of the wrong soil type soil moisture coefficients caused soil moisture to be greatly undermeasured (a typical wrong value was 4% instead of the correct 17%), soil heat flows to be undermeasured, and sensible and latent heat fluxes to be overestimated. Soil heat flow plate outputs were undermeasured by up to 10%, change of energy storage was undermeasured by up to 80% and total soil heat flow was undermeasured by up to 50% as a result. This would result in approximately a 5% overestimation of both sensible and latent heat fluxes.

Subject:	SGP/EBBR/E15 - Improved EBBR CR10 Program
DataStreams:	sgp30ebbrE15.b1
Description:	Effective 20050329.1900, the EBBR.E15 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 sgp30ebbrE15.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE15.a1).

Subject:	SGP/EBBR/E15 - Water in dome
DataStreams:	sgp15ebbrE15.b1, sgp30ebbrE15.b1, sgp5ebbrE15.b1
Description:	There was water in the bottom dome of the net radiometer. Net radiation, and sensible and latent heat fluxes were incorrect during the period.
Measurements:	sgp15ebbrE15.b1: Net radiation(mv_q) sgp30ebbrE15.b1: net radiation(q) latent heat flux(e) h(h) sgp5ebbrE15.b1: net radiation(q)

Subject:	SGP/EBBR/E15 - Soil Heat Flow #4 Incorrect
DataStreams:	sgp15ebbrE15.b1, sgp30ebbrE15.b1
Description:	Soil heat flux #4 produced too large a soil heat flow at times, resulting in it exceeding the qc check limit and causing sensible and latent heat fluxes to be incorrect.
Measurements:	sgp15ebbrE15.b1: Soil heat flow 4(mv_hft4) sgp30ebbrE15.b1: latent heat flux(e) 5 cm soil heat flow, site 4(shf4) 5 cm soil heat flow corrected for soil moisture content, site 4(c_shf4) average surface soil heat flow(ave_shf) soil heat flow, site 4(g4) h(h)
