SGP/ECOR/E16 - Data suspect due to inability to run QC
DataStreams:sgp30ecorE16.b1, sgpecorE16.00
Some QC checks were unsuccessful due to a communication failure that resulted in 
contaminated QC field data.

All the data that are based on water vapor density and CO2 concentration are "suspect" 
because many of the standard QC checks were not employed.
The wind, temp, sensible heat flux, and momentum flux were not affected.
