SGP/EBBR/E19 - Incorrect Sensible and Latent Heat Fluxes
DataStreams:sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:
The gradient measurements and latent and sensible heat fluxes were incorrect because the 
AEM was not exchanging. 

The problem was fixed by replacing the AEM.
Measurements:sgp5ebbrE19.b1:
  • bottom vapor pressure(vp_bot)
  • Bottom humidity(hum_bot)
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • top air temperature(tair_top)
  • top vapor pressure(vp_top)
  • bottom air temperature(tair_bot)
  • Top humidity(hum_top)
  • Temperature of the top humidity chamber(thum_top)

sgp15ebbrE19.b1:
  • Right air temperature(tair_r)
  • Left air temperature(tair_l)

sgp30ebbrE19.b1:
  • top vapor pressure(vp_top)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • h(h)
  • Temperature of the top humidity chamber(thum_top)
  • top air temperature(tair_top)
  • soil heat flow, site 1(g1)
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • Top humidity(hum_top)
  • bottom vapor pressure(vp_bot)
  • latent heat flux(e)
  • Bottom humidity(hum_bot)
  • bottom air temperature(tair_bot)

SGP/EBBR/E19 - Sensible and latent heat flux and net radiation incorrect
DataStreams:sgp15ebbrE19.b1, sgp30ebbrE19.b1, sgp5ebbrE19.b1
Description:
Net radiation was too large, resulting in sensible and latent heat fluxes being too large. 
 The cause of the problem is unknown.
Measurements:sgp5ebbrE19.b1:
  • net radiation(q)

sgp15ebbrE19.b1:
  • Net radiation(mv_q)

  • h(h)
  • latent heat flux(e)
