Subject:	SGP/CO2FLX/C1 - Reprocessed: User Notes
DataStreams:	sgp30co2flx4mmetC1.b1
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.
Measurements:	sgp30co2flx4mmetC1.b1: ppfd_up Total downwelling shortwave radiation (LI-200 sensor)(r_tot)

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.

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.

DataStreams:	sgp30co2flx4mC1.b1
Description:	The 4m CO2 flux system was calibrated on May 25, 2005. After the calibration was performed, calibration coefficients used to measure CO2 density were not updated. This added an OFFSET to the CO2 density measurements. The data have been reprocessed to address the offset. The reprocessed data were archived in December 2008. Please retrieve the updated files for use in your analysis.
