SGP/EBBR/E13 - Net Radiometer Tilted Half Degree West
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:
The net radiation daily peak on sunny days occured 1/2 hour after the net radiation peak 
at E2, E9, and the SIRS because the sensor was tipped to the west about 1/2 degree.
Measurements:sgp15ebbrE13.b1:
  • Net radiation(mv_q)
sgp5ebbrE13.b1:
  • net radiation(q)
sgp30ebbrE13.b1:
  • net radiation(q)
  • latent heat flux(e)
  • h(h)

SGP/EBBR/E13 - Sensible and Latent Heat Fluxes Incorrect (AEM failure)
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:
The AEM was stuck in the home 30 position most of this period.

Therefore, the sensible and latent heat fluxes are incorrect during most of this period.
Measurements:sgp15ebbrE13.b1:
  • Left air temperature(tair_l)
  • Right air temperature(tair_r)
sgp5ebbrE13.b1:
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • top vapor pressure(vp_top)
  • top air temperature(tair_top)
  • Temperature of the top humidity chamber(thum_top)
  • bottom vapor pressure(vp_bot)
  • bottom air temperature(tair_bot)
sgp30ebbrE13.b1:
  • Bottom humidity(hum_bot)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • bottom vapor pressure(vp_bot)
  • Temperature of bottom humidity sensor chamber(thum_bot)
  • Temperature of the top humidity chamber(thum_top)
  • latent heat flux(e)
  • h(h)
  • bottom air temperature(tair_bot)
  • top air temperature(tair_top)
  • Top humidity(hum_top)
  • top vapor pressure(vp_top)

SGP/EBBR/E13 - Loose connections
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:
The tair_bot spiked around midday, as if it is temperature related, and may have indicated 
a loose connection.

The sensible and latyent heat fluxes and Bowen ratio were incorrect when this condition 
occurred.
Measurements:sgp15ebbrE13.b1:
  • Left air temperature(tair_l)
  • Right air temperature(tair_r)
sgp5ebbrE13.b1:
  • bottom air temperature(tair_bot)
sgp30ebbrE13.b1:
  • bottom air temperature(tair_bot)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • latent heat flux(e)

SGP/EBBR/E13 - metadata corrections
DataStreams:sgp15ebbrE13.b1, sgp30ebbrE13.b1, sgp5ebbrE13.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E13 data collected by ARM back to the installation of the 
instrument in September 1992.  Please see the current metadata for correct information.  
These changes do not affect data values or quality.

The changes are summarized below:
1) Update of "sensor location" information
2) Addition of installation dates for systems
3) Correction of soil type
4) Correction of soil moisture units (from "by volume" to "gravimetric")
