Subject:
SGP/EBBR/E12 - 3-month check
DataStreams:sgp5ebbrE12.b1, sgp30ebbrE12.b1, sgp15ebbrE12.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.  The period of incorrect
data for the EBBR is listed above; data times affected do not include the
beginning time and do include the ending time (data files are denoted by
the end time).
Suggestions: 
Measurements:sgp15ebbrE12.b1:
  • Right T/RH sensor temperature (resistance ratio)(temp_trh_right_rr)
  • Left T/RH sensor temperature (resistance ratio)(temp_trh_left_rr)
  • Left air temperature(temp_air_left)
  • Right relative humidity (mV)(rh_right_mv)
  • Left relative humidity (mV)(rh_left_mv)
  • Right air temperature(temp_air_right)
