SGP/EBBR/E7 - Radiation Shield Problem
DataStreams:sgp5ebbrE7.b1, sgp30ebbrE7.b1
Description:
The right radiation shield was out of position or off during the period of
time indicated.  This may or may not have occurred as a result of preventative
maintenance on November 15.  All air and humidity probe temperatures (except
the reference temperature), relative humidities, vapor pressures, Bowen ratio,
sensible heat flux, and latent heat flux during this period are questionable.
During a large part of the period the resultant sensible and latent heat fluxes
look reasonable.  However, during part of the period, the difference in
relative humidity between the two EBBR levels appears to be much too large.
Unusual differences in temperatures are not as obvious.
Suggestions: 
Measurements:sgp5ebbrE7.b1:
  • Bottom vapor pressure(vapor_pressure_bottom)
  • Top vapor pressure(vapor_pressure_top)
  • Bottom relative humidity (fractional)(rh_bottom_fraction)
  • Bottom air temperature(temp_air_bottom)
  • Top relative humidity (fractional)(rh_top_fraction)
  • Top T/RH sensor temperature(temp_trh_top)
  • Bottom T/RH sensor temperature(temp_trh_bottom)
  • Top air temperature(temp_air_top)
