SGP/ECOR/E5 - CO2/H2O Fluxes Incorrect All Times, All Measurements Incorrect Sometimes
DataStreams:sgp30ecorE5.b1
Description:
A problem with garbled sonic anemometer data sometimes occurred (causing all data to be 
incorrect), but this first followed a failure of analog communications with the LI-7500; 
LI-7500 analog measurements (but not the measurements communicated through the serial line) 
were incorrect during the entire period.

It is unclear at this point what initiated the problem.
