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:	Replacement of LI-200 sensor (total downwelling shortwave radiation, variable r_tot) by a new LI-190 sensor (upwelling photosynthetic photon flux density, variable ppfd_up). The new LI-190 sensor was: - installed on December 9, 2004. - being tested from December 9, 2004 to December 22, 2004. - operational after December 22, 2004. Consequently: 1. variable "r_tot" is filled with missing values (qc_r_tot = 1) after December 9, 2004, 2. variable "ppfd_up" is filled with missing values (qc_ppfd_up = 1) prior December 22, 2004.

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.

Subject:	SGP/CO2FLX/C1 - downwelling longwave hemispheric irradiance incorrect
DataStreams:	sgp30co2flx4mmetC1.b1
Description:	A problem was identified with the downwelling longwave hemispheric irradiance (variable "r_down_long_hemisp") calibration of our Kipp & Zonen CNR1 radiometer. The offset of the instrument is believed to be incorrect over the specified time frame, and a correction of the problem is underway.
