Description:	The infrared gas analyzer (IRGA) failed on Nov. 2, 2004, 02:00; the system continued to operate without H2O and CO2 data until Nov. 9, 2004, 15:30; then it stopped due to another hardware failure. The system was returned to service on Nov. 12, 2004, 18:00. The latent heat flux and CO2 flux data are irrevocably lost for the period from Nov. 2, 2004, 02:00 to Nov. 12, 2004, 18:00.

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.

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.

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.

Subject:	SGP/ECOR/E10 - Reprocess: Wind Direction Incorrect
DataStreams:	sgp30ecorE10.b1
Description:	It was discovered that the E10 ECOR boom is aligned 17 degrees to the west of true north. Therefore, all wind direction data for the stated period is 17 degrees too high. Subtract 17 degrees from the wind direction to give the correct direction. The E10 configuration file was modified to correct this problem.
Measurements:	sgp30ecorE10.b1: wind_dir
