SGP/ECOR/E3 - Failed IRGA

Infrared gas analyzer (IRGA) failed 6/16; a new IRGA was installed on
6/30.  All data related to CO2 and water vapor concentration measurements
(including CO2 flux and latent heat flux) are incorrect for the period of
June 16, 2004, 17:30 to June 30, 2004, 17:30.  Wind and sensible heat flux data are OK.

SGP/ECOR/E3 - Data transfer problem

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/E3 - CO2/H2O Sensor Not Working

The CO2/H2O sensor failed.  Means and fluxes of CO2 and H2O (lv_e) are incorrect or 
missing.

SGP/ECOR/E3 - Pressure and Temperature Missing

Pressure and temperature from the LI-7500 are missing. This did not affect the sensible 
and latent heat fluxes, however, much of the ECOR data is missing during this period.

Attempts to correct the problem were unsuccessful until the time of site decommissioning. 
This facility was decommissioned and maintenance efforts ceased 10/1/2009.
