Subject:	SGP/ECOR/E24 - Reprocess: Sonic analog input failure
DataStreams:	sgp30ecorE24.b1
Description:	All the data based on H2O and CO2 "analog signals" (latent heat flux, CO2 flux, etc.) are incorrect for the period of 10:00 June 4, 2004 to 17:30 Sept. 16, 2004 due to to failure in sonic anemometer analog input circuitry. Correct water vapor density and CO2 concentration data are stored in IRGA (infrared gas analyzer) raw data files (sgpecorE24.00 datastream); that data may be used to re-calculate fluxes.

Subject:	SGP/ECOR/E24 - Reprocess: Incorrectly flagged (marked as "bad") H2O/CO2 data
DataStreams:	sgp30ecorE24.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. Below is a list of times when that might have happen.
