Subject: SGP/CO2FLX/C1 - Reprocessed: Recalibration
Affected 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.
Measurements
  • mean_c (Mean CO2 density)
  • mean_c (mean CO2 density)
