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.
