DataStreams:sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:
The E7 pressure sensor suffered
from spikes in pressure, which were related to 
increases in voltage during the day as the 
solar panels charged the battery.  These spikes
were not of a magnitude that would affect the 
30 minute surface fluxes.

Replacement of the pressure sensor solved the problem.

SGP/EBBR/E7 - metadata corrections
DataStreams:sgp15ebbrE7.b1, sgp30ebbrE7.b1, sgp5ebbrE7.b1
Description:
On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E7 data collected by ARM back to the installation of the 
instrument in May 1993. 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")

SGP/ECOR/E10 - CO2 and Latent Heat Fluxes Incorrect
DataStreams:sgp30ecorE10.b1
Description:
The CO2 and latent heat fluxes were incorrect because the sonic anemometer was not working 
properly.

  • rotated covariance wc(cvar_rot_wc)
  • covariance wc(cvar_wc)
  • variance of c(var_c)
  • variance of q(var_q)
  • latent heat flux(lv_e)
  • CO2 flux(fc)
  • Water vapor density (q)(mean_q)
  • covariance wq(cvar_wq)
  • rotated covariance wq(cvar_rot_wq)

SGP/ECOR/E10 - Incorrect CO2 fluxes
DataStreams:sgp30ecorE10.b1
Description:
The analog CO2 signal from the LI-7500 to the sonic anemometer became very noisy and 
incorrect CO2 fluxes resulted. Sonic anemometer was replaced.
Measurements:sgp30ecorE10.b1:
  • CO2 flux(fc)
