SGP/EBBR/E13 - Sensible and Latent Heat Fluxes Incorrect (AEM failure)
DataStreams:sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.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 the bottom humidity sensor chamber(thum_bot)
  • top vapor pressure(vp_top)
  • top air temperature(tair_top)
  • temperature of the top humidity sensor chamber(thum_top)
  • bottom vapor pressure(vp_bot)
  • bottom air temperature(tair_bot)
sgp30ebbrE13.b1:
  • bottom relative humidity(hum_bot)
  • ratio of sensible/latent heat fluxes (Bowen ratio)(bowen)
  • bottom vapor pressure(vp_bot)
  • temperature of the bottom humidity sensor chamber(thum_bot)
  • temperature of the top humidity sensor chamber(thum_top)
  • latent heat flux(e)
  • corrected sensible heat flux(h)
  • bottom air temperature(tair_bot)
  • top air temperature(tair_top)
  • top relative humidity(hum_top)
  • top vapor pressure(vp_top)

SGP/EBBR/E13 - metadata corrections
DataStreams:sgp5ebbrE13.b1, sgp15ebbrE13.b1, sgp30ebbrE13.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")
