SGP/EBBR/E27 - Net Radiation Incorrect; Sensible and Latent Heat Fluxes Incorrect
DataStreams:sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:
The net radiometer top dome was broken and water got inside, making the net radiation, and 
sensible and latent heat flux measurements incorrect.
Measurements:sgp5ebbrE27.b1:
  • net radiation(q)
sgp30ebbrE27.b1:
  • h(h)
  • latent heat flux(e)
  • net radiation(q)

DataStreams:sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:
Residual Moisture left in the top dome of the net radiometer after the 8/17/05 servicing 
caused the net radiation measurements to be biased low, and resulting in sensible and 
latent heat flux being low also.
Measurements:sgp5ebbrE27.b1:
  • net radiation(q)

  • h(h)
  • latent heat flux(e)

SGP/EBBR/E27 - metadata corrections
DataStreams:sgp15ebbrE27.b1, sgp30ebbrE27.b1, sgp5ebbrE27.b1
Description:
On 20050816, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E27 data collected by ARM back to the installation of the 
instrument in May 2003. 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 the systems
3) Correction of soil moisture units (from "by volume" to "gravimetric")
