SGP/EBBR/E2 - Net Radiation and Fluxes Incorrect
DataStreams:sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:
The net radiometer was tipped 37 degrees eastward, resulting in apparent
solar noon being 2.5 hours early.  The net radiation error results in incorrect sensible 
and latent heat fluxes.
Measurements:sgp30ebbrE2.b1:
  • h(h)
  • latent heat flux(e)
  • net radiation(q)
sgp15ebbrE2.b1:
  • Net radiation(mv_q)

Subject:
SGP/EBBR/E2 - AEM Ventilator Dangling - Sensible and Latent Heat Fluxes Incorrect
DataStreams:sgp15ebbrE2.b1, sgp30ebbrE2.b1, sgp5ebbrE2.b1
Description:
The right AEM ventilator unit with temperature and humidity sensors inside was dangling 
from the AEM.  Therefore, the gradients of temperature and relative humidity and thus 
sensible and latent heat flux are suspect for this period.  Often, the fluxes look reasonable.
Measurements:sgp15ebbrE2.b1:
  • Right air temperature(tair_r)
  • Temperature of right humidity sensor chamber(rr_thum_r)
  • Right relative humidity(mv_hum_r)
sgp5ebbrE2.b1:
  • Temperature of the top humidity chamber(thum_top)
  • top air temperature(tair_top)
  • top vapor pressure(vp_top)
  • Top humidity(hum_top)
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • Bottom humidity(hum_bot)
  • bottom air temperature(tair_bot)
  • bottom vapor pressure(vp_bot)
sgp30ebbrE2.b1:
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • top air temperature(tair_top)
  • bottom vapor pressure(vp_bot)
  • bottom air temperature(tair_bot)
  • latent heat flux(e)
  • h(h)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • Bottom humidity(hum_bot)
  • top vapor pressure(vp_top)
