Subject:
SGP/ECOR/E10 - Reprocess: Incorrectly flagged (marked as "bad") H2O/CO2 data
DataStreams:sgp30ecorE10.b1
Description:
Due to system clock instability on ECOR computers their system time is adjusted 
approximately once per hour; sometimes this adjustment leads to backward time jumps over midnight, 
into the previous day. In this case all the data based on CO2/H2O measurements might be 
erroneously marked as bad.
Suggestions: 
Correct data may be restored by reprocessing raw data (sonic and IRGA, 00 level) with 

current ECOR processing program (version 1.9 or later).
