Subject:	SGP/ECOR/E14 - CO2/H2O Incorrect
DataStreams:	sgp30ecorE14.b1
Description:	The LI-7500 CO2/H2O sensor stopped working after a rainstorm. CO2 and H2O data are incorrect during the stated period.

Subject:	SGP/ECOR/E14 - Flux Measurements Incorrect
DataStreams:	sgp30ecorE14.b1
Description:	The ECOR datastream was corrupted; this happens when the ECOR program produces a datastream of the wrong length (i.e., leaves one or more measurements out). Fluxes and some other measurements are incorrect. Reprocessing will not correct this problem; the raw data are corrupted.
Measurements:	sgp30ecorE14.b1: Mean H2O density(mean_q) Corrected sensible heat flux(h) atm_pres Mean CO2 density(mean_c) temp_irga CO2 flux(fc) Latent heat flux(lv_e)

Subject:	SGP/ECOR/E14 - Fluxes and Most Measurements Incorrect
DataStreams:	sgp30ecorE14.b1

Subject:	SGP/ECOR/E14 - IRGA Temperature Incorrect or Missing
DataStreams:	sgp30ecorE14.b1
Description:	The temp_irga was too large 05/09/07 1300 GMT - 05/10/07 2000 GMT. The temp_irga was flat lined at 49.96 C 05/10/07 2030 GMT - 05/17/07 2000 GMT. The temp_irga was missing 05/17/07 2030 GMT - 05/19/07 1700 GMT.
Measurements:	sgp30ecorE14.b1: temp_irga

Subject:	SGP/ECOR/E14 - Sensor failure
DataStreams:	sgp30ecorE14.b1
Description:	The water vapor output of the LI-7500 was too low, indicating that water vapor leaked into the sensor and that the chemicals are spent or there was an electronic failure. Latent heat flux was not normally affected by this problem.
Measurements:	sgp30ecorE14.b1: Mean H2O density(mean_q)
