2041 2015-11-03 Vaira CO2 probe North Profile -0.04 Removed Lab none Removed from Vaira North profile at -4cm due to bad readings. Replaced by sn L2010068
2065 2014-12-09 Vaira CO2 probe North Profile -0.04 Location Vaira CO2 probe North Profile -0.04 Vaira North profile at -4cm - may have been at -2cm
2012 2014-04-22 Vaira CO2 probe North Profile -0.02 Moved Vaira CO2 probe North Profile -0.04 At Vaira North profile, moved from -2cm to -4cm.
1996 2014-01-29 Lab none Installed Vaira CO2 probe North Profile -0.02 Installed at Vaira in the North profile as -2cm with new U-shaped tops on the PVC enclosures.
1439 2014-01-27 Lab none Calibration Lab none Trueppm = Probeppm*1.01 + 67.88; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 3056ppm, and 10000ppm. Ta=22.7C, P=102.1kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Patty.
1187 2014-01-24 Vaira CO2 probe North Profile -0.02 Removed Lab none Removed from Vaira north plot at -2cm for lab calibration
1121 2012-03-21 Lab none Installed Vaira CO2 probe North Profile -0.02 Installed at Vaira in the north set at -2cm
1396 2012-01-30 Lab none Calibration Lab none Trueppm = Probeppm*1.02 + 31.82; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 436ppm, 2238ppm, and 10000ppm (N2 bal). Ta=27.4C, P=101.9kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan.
1384 2011-03-14 Lab none Calibration Lab none Trueppm = Probeppm*1.046 + 56.59; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 597ppm, 2238ppm, and 10000ppm (N2 bal). Ta=25.3C, P=102.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied.
