Subject: SGP EBBR E13 - E13 EBBR AEM Home 30 Offset or AEM in Mid Position
Affected Datastreams: sgp5ebbrE13.b1
Description The AEM stopped before reaching the end of it's travel, causing the home signals to be between 0 and 3 during part of this period. 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. All gradient data, sensible heat flux, latent heat flux, and the Bowen ratio are incorrect during these conditions.

Subject: SGP EBBR E13 - E13 EBBR Left Air Temperature Incorrect
Affected Datastreams: sgp30ebbrE13.b1
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.

Subject: SGP EBBR E13 - E13 EBBR AEM Home 30 Offset
Affected Datastreams: sgp30ebbrE13.b1
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 - E13 EBBR AEM in Mid Position
Affected Datastreams: sgp5ebbrE13.b1
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.

Affected Datastreams: 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.

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.

Description The EBBR Net Radiation (Rn) values maintained a ~200 Wm^-2 reading because of poor cable lead connections. Sensible and latent heat fluxes were therefore overestimated. Sensible (H) and latent heat (LE) fluxes can be estimated in the following way: H (new) = H/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation] LE (new) = LE/[1 + (EBBR Rn - SIRS net radiation)/SIRS net radiation]
Measurements
  • net_radiation (Net radiation)
  • sensible_heat_flux (Sensible heat flux)
  • latent_heat_flux (Latent heat flux)

Subject: SGP/EBBR/E7 - 3-Month Check
Affected Datastreams: sgp30ebbrE7.b1
Description During EBBR 3 month checks the Automatic Exchange Mechanism is disabled (reflected by home signals near zero) so that the two aspirator units can be placed at the same height. The measurements during these periods do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), or latent heat flux (e), nor do the air temperature and relative humidity measurements indicate correct gradients. Checks performed before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for the period above.

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).

Subject: SGP/EBBR/E9 - Temperature Portion of T/RH Probe
Affected Datastreams: sgp30ebbrE9.b1
Description The Temperature portion of the right T/RH probe indicated too high a temperature for nearly 11 months. I twice placed work requests to have the probe replaced, but no spares were available. Spares recently became available and I placed a new work request to have the probe changed. The replacement occurred on 18 June 1997; this fixed the problem. The main results of the high temperatures were probe top and bottom temperatures (used only for the calculation of vapor pressure) and vapor pressures that were too large. Furthermore, this caused latent heat flux to be reported to be too large, and therefore sensible heat flux was reported to be too small. Recalculation of the fluxes using thermocouple temperatures to calculate vapor pressure would be quite time consuming and would have to assume that the thermocouple temperature and probe temperature were nearly the same. The EBBR procedures have been changed to include comparison of the thermocouple and probe temperatures to make it easier for the site operators to detect this condition. The data affected (and thus incorrect) includes: 15 minute: rr_thum_r 30 minute: thum_top, thum_bot, vp_top, vp_bot, e, h, bowen.

Subject: SGP/EBBR/E9 - EBBR Net Radiometer Domes Pierced, Water Inside - Data Affected
Affected Datastreams: sgp30ebbrE9.b1
Description The upper dome of the EBBR net radiometers was punctured. After the puncture, water collected in the top and/or bottom dome. The water was removed and the dome was replaced during PM visits. In some cases, the puncture and water resulted in incorrect data. Comparison with net radiation values from surrounding EBBR sites and the SIRS is neccesary to determine if the EBBR net radiation data are correct or incorrect. It is often difficult to tell from the data when the punctures occurred, but they would have existed for no more than 2 weeks, since the domes are checked during each two-weekly PM visit. Incorrect net radiation data results in the latent heat flux and sensible heat flux also being incorrect.

Subject: SGP/EBBR/E9 - Six Month Checks
Affected Datastreams: sgp5ebbrE9.b1
Description During EBBR 6 month checks (formally called 3 month checks) the Automatic Exchange Mechanism is disabled (reflected by home signals near zero) so that the two aspirator units can be placed at the same height. The measurements during these periods do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), or latent heat flux (e), nor do the air temperature and relative humidity measurements indicate correct gradients. Checks performed just before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for the period above.

Description During EBBR 6 month checks (formally called 3 month checks) the Automatic Exchange Mechanism is disabled (reflected by home signals near zero) so that the two aspirator units can be placed at the same height. The measurements during these periods do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), or latent heat flux (e), nor do the air temperature and relative humidity measurements indicate correct gradients. Checks performed just before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for the period indicated.

Subject: SGP/EBBR/E13 - Left T/RH Probe Temperature Incorrect
Affected Datastreams: sgp30ebbrE13.b1
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.

  • vapor_pressure_bottom (Bottom vapor pressure)
  • sensible_heat_flux (Sensible heat flux)

Subject: SGP/EBBR/E9 - Right Humidity Suspect
Affected Datastreams: sgp5ebbrE9.b1
Description The Right Humidity measurement was normally incorrect, although it is often difficult to determine it by looking at the measurement. The measurements float around, sometimes being too large and sometimes being too small, through most of the day, particularly for the hour before sunset through the hour after sunrise. Great care and comparison with surrounding EBBR sites would be needed to be able to use any of the latent and sensible heat flux measurements from E9 for this period. Another DQPR has been issued to fix this problem, which has eluded repair efforts so far.

Subject: SGP/EBBR/E7 - Six-Month Checks
Affected Datastreams: sgp30ebbrE7.b1
Description During EBBR 6 month checks (formally called 3 month checks) the Automatic Exchange Mechanism is disabled (reflected by home signals near zero) so that the two aspirator units can be placed at the same height. The measurements during these periods do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), or latent heat flux (e), nor do the air temperature and relative humidity measurements indicate correct gradients. Checks performed just before or after the AEM is disabled also lead to some incorrect data. Incorrect 5, 15 minute and half hour data occurs for the period above.

Subject: SGP/EBBR/E9 - Wind Direction Sensor Malfunction
Affected Datastreams: sgp5ebbrE9.b1
Description During numerous intermittent times during the period listed, the wind direction sensor at E9, Ashton, KS malfunctioned, putting out a value of 135. The sensor was replaced on 30 September 1997, at 1550 GMT. All wind direction data with values of 135 during the period listed should be considered incorrect. The affected data are: 5 minute: res_ws, wind_d, sigma_d 15 minute: mv_wind_d 30 minute: res_ws, wind_d, sigma_d
Measurements
  • wspd_vec_mean (Wind speed vector mean)
  • wdir_vec_std (Wind direction vector mean standard deviation)
  • wdir_vec_mean (Wind direction vector mean)

Subject: SGP/EBBR/E7 - Improved EBBR CR10 Program
Affected Datastreams: sgp30ebbrE7.b1
Description Effective 20050322.1900, the EBBR.E7 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 20050322, 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 sgp30ebbrE7.b1 data stream. The earlier version of the CR10 program was also used on previous EBBR datastream names (e.g. sgp30ebbrE7.a1).
Measurements
  • surface_soil_heat_flux_avg (Surface soil heat flux, average of fluxes 1-5)
  • latent_heat_flux (Latent heat flux)

Subject: SGP/EBBR/E13 - Water In Net Radiometer; Surface Fluxes are Incorrect
Affected Datastreams: sgp5ebbrE13.b1
Description The net radiometer top dome was punctured by migrating birds. This alone does not cause incorrect net radiation measurements. However, when it subsequently rains, water collects in the bottom dome, causing the net radiation measurements to be too large during the day and too small at night.
Measurements
