SGP/ECOR/E14 - CO2/H2O Fluxes Incorrect All Times, All Measurements Incorrect Sometimes
DataStreams:sgp30ecorE14.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.

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 measurements out).

Fluxes and some other measurements are incorrect.

Note: Mentor reports reprocessing will not correct this problem.
