DataStreams:	sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1
Description:	Soil Heat Flow probes #1 and #2 were incorrect during the indicated period (and for some time afterward, to be covered in another DQR). Outputs from the probes were typically too large negative or too large positive.

DataStreams:	sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1
Description:	The left T/RH Probe Temperature was often incorrect, causing the other indicated measurements to be incorrect also. When the home30 signal had an offset, the top RH probe temperature was incorrect but not the bottom RH probe temperature.

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.

Subject:	SGP EBBR E13 - E13 EBBR AEM Home 30 Offset

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. All gradient data, sensible heat flux, latent heat flux, and the Bowen ratio are incorrect during this condition.

Subject:	SGP/EBBR/E13 - Left T/RH Probe Temperature Incorrect
DataStreams:	sgp15ebbrE13.a1, sgp15ebbrE13.b1, sgp30ebbrE13.a1, sgp30ebbrE13.b1, sgp5ebbrE13.a1
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.
Measurements:	sgp15ebbrE13.b1: temp_trh_left_rr sgp15ebbrE13.a1: Temperature of left humidity sensor chamber(rr_thum_l) sgp5ebbrE13.a1: bottom vapor pressure(vp_bot) Temperature of bottom humidity sensor chamber(thum_bot) sgp30ebbrE13.b1: latent_heat_flux sensible_heat_flux bowen_ratio temp_trh_bottom vapor_pressure_bottom sgp30ebbrE13.a1: latent heat flux(e) Temperature of bottom humidity sensor chamber(thum_bot) bottom vapor pressure(vp_bot) ratio of sensible/latent heat fluxes (Bowen ratio)(bowen) h(h)

Description:	The automatic exchange mechanism hung numerous times, but with various different measurements of home signals. 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 - Net Radiometer Iced Over During Storm
DataStreams:	sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:	The net radiometer was covered with ice from a storm. Net radiation values are incorrect, and are sometimes even negative during the daytime. Sensible and latent heat fluxes are therefore incorrect.
Measurements:	sgp15ebbrE13.b1: net_radiation_mv sgp5ebbrE13.b1: net_radiation sgp30ebbrE13.b1: latent_heat_flux net_radiation sensible_heat_flux

Subject:	SGP/EBBR/E13 - Wind Speed Frozen Stopped By Ice
DataStreams:	sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:	An ice storm froze the wind speed sensor to a stopped condition. The wind speed and residual wind speed measurements are incorrect. This sensor failure does not affect the sensible and latent heat fluxes.

Subject:	SGP/EBBR/E13 - Automatic Exchange Mechanism Failure
DataStreams:	sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:	The AEM was stuck in the home_15 position or reported near zero home signals during much of the indicated period. The Bowen ratio and latent and sensible heat fluxes were incorrect when the AEM was not operating properly; the periods of incorrect data can be determined from the home signal values. On 7/14/04 the AEM was replaced.

Subject:	SGP/EBBR/E13 - metadata corrections
DataStreams:	sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:	On 20050723, a series of metadata corrections and additions were completed. These metadata changes apply to all EBBR.E13 data collected by ARM back to the installation of the instrument in September 1992. 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 systems 3) Correction of soil type 4) Correction of soil moisture units (from "by volume" to "gravimetric")
