Subject:	SGP/ECOR/E10 - Reprocess: Incorrect H2O, CO2
DataStreams:	sgpecorE10.00, sgp30ecorE10.b1
Description:	Due to failure of analog output circuitry in the Infrared Gas Analyzer (IRGA), CO2 and water vapor parameters measured by the IRGA (water vapor density, CO2 concentration, fluxes of latent heat and CO2) were incorrectly recorded in sonic raw data files for the period of 22:30 Dec. 14, 2004 to 22:00 Jan. 11, 2005. The data could be recovered from IRGA raw serial files (00 level).

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.
