Subject:
SGP/ECOR/E3 - Data transfer problem
DataStreams:sgpecorE3.00, sgp30ecorE3.b1
Description:
Serial communication with one sensor (the IRGA) were partially disrupted due to 
deteriorating hardware from 13:53, Dec. 19, 2004 to 09:31 Dec. 20, 2004.  Serial data from the IRGA 
is mainly used to get sensor status codes, so this might lead to false increase of "bad" 
point count.  It seems that IRGA analog outputs (stored in raw sonic data file,  primary 
source of data) were not affected, so the flux data may be reprocessed or verified using 
raw sonic data files and ignoring IRGA sensor status.
