SGP/EBBR/E8 - 3-month Check
DataStreams:sgp30ebbrE8.b1, sgp15ebbrE8.b1, sgp5ebbrE8.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 this period, at least,
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 gradients.  Checks performed before or after the AEM
is disabled also lead to some incorrect data.
Suggestions:

  • Bottom air temperature(temp_air_bottom)
  • Bottom relative humidity (fractional)(rh_bottom_fraction)
  • Bottom T/RH sensor temperature(temp_trh_bottom)
  • Bottom vapor pressure(vapor_pressure_bottom)
  • Top relative humidity (fractional)(rh_top_fraction)
  • Top vapor pressure(vapor_pressure_top)
  • Top air temperature(temp_air_top)
