SGP/ECOR/E3 - Data transfer problem
DataStreams:sgp30ecorE3.b1, sgpecorE3.00
Description:
Serial communication with one sensor (the IRGA) were partially disrupted due to 
deteriorating hardware from 13:53, Dec. 19, 2004 to 09:31 Dec. 20, 2004.  Serial data from the IRGA 
is mainly used to get sensor status codes, so this might lead to false increase of "bad" 
point count.  It seems that IRGA analog outputs (stored in raw sonic data file,  primary 
source of data) were not affected, so the flux data may be reprocessed or verified using 
raw sonic data files and ignoring IRGA sensor status.

SGP/ECOR/E21 - Intermittent incorrect flux measurements
DataStreams:sgp30ecorE21.b1
Description:
At various times during the period, the LI-7500 CO2/H2O serial and analog signals from the 
LI-7500 were missing, but usually not at the same time.

When the CO2/H2O serial datastream was missing, the Pressure and Temperature were missing; 
this did not, in itself, result in incorrect fluxes, as default values for pressure and 
temperature are automatically used.

Fluxes were incorrect when the CO2/H2O analog datastream was missing; these
times are identified by the qc checks.
Measurements:sgp30ecorE21.b1:
  • latent heat flux(lv_e)
  • covariance wc(cvar_wc)
  • average atmospheric pressure (IGRA internal sensor)(atm_pres)
  • covariance wq(cvar_wq)
