Subject: SGP/EBBR/E13 - Wind Speed Sensor Frozen
Affected Datastreams: sgp5ebbrE13.b1
Description The wind speed sensor was frozen during the period. Data values that were incorrect are: 5 minute: wind_s, res_ws 15 minute: wind_s 30 minute: wind_s, res_ws
Measurements
  • wspd_arith_mean (Wind speed arithmetic mean)
  • wspd_vec_mean (Wind speed vector mean)

Subject: SGP/EBBR/E13 - EBBR AEMs Not Exchanging (Iced Or Fuse Blown)
Affected Datastreams: sgp5ebbrE13.b1
Description The EBBR AEM stopped exchanging because of icing at during this time period. The calculations of Bowen ratio, latent heat flux, and sensible heat flux are incorrect for the time period indicated. The other measurements listed are also incorrect for those times: Note: Mentor supplied the end date/time for this DQR after submittal
Measurements
  • sensible_heat_flux (Sensible heat flux)
  • temp_air_bottom (Bottom air temperature)
  • rh_top_fraction (Top relative humidity (fractional))
  • latent_heat_flux (Latent heat flux)
  • vapor_pressure_top (Top vapor pressure)
  • bowen_ratio (Bowen ratio)
  • temp_trh_bottom (Bottom T/RH sensor temperature)
  • vapor_pressure_bottom (Bottom vapor pressure)
  • temp_air_top (Top air temperature)
  • rh_bottom_fraction (Bottom relative humidity (fractional))
  • temp_trh_top (Top T/RH sensor temperature)

Subject: SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR Header
Affected Datastreams: sgp30ebbrE26.b1
Description The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the EBBR 30 minute netcdf header have been incorrect from the beginning of processing the data into netcdf files. The correct units are MJ/m^3/C. This does not affect the data quality. (NOTE: The actual begin date of some of these data streams is as early as 7/4/93. This DQR applies to all 30m EBBR data.)
Measurements
  • soil_heat_capacity_4 (Soil heat capacity 4)
  • soil_heat_capacity_5 (Soil heat capacity 5)
  • soil_heat_capacity_1 (Soil heat capacity 1)
  • soil_heat_capacity_3 (Soil heat capacity 3)
  • soil_heat_capacity_2 (Soil heat capacity 2)

Subject: SGP/EBBR/E13- EBBR Frozen Wind Speed
Affected Datastreams: sgp15ebbrE13.b1
Description Wind speed cups were frozen during the indicated time periods. All 5, 15, and 30 minute data values indicated are incorrect for the periods listed.
Measurements
  • wspd_arith_mean (Wind speed arithmetic mean)
  • wspd_vec_mean (Wind speed vector mean)
