Subject:	SGP/ECOR/E3 - Data transfer problem
DataStreams:	sgpecorE3.00, sgp30ecorE3.b1
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.

Subject:	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.

Subject:	SGP/ECOR/E3 - Pressure and Temperature Missing
DataStreams:	sgp30ecorE3.b1
Description:	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.
Measurements:	sgp30ecorE3.b1: temp_irga atm_pres
