3020 2017-08-25 Tonzi Notes Lab none We removed the CO2 probe at the Tree 2 profile at -2 cm position. The probe was sn Z2720014. Not sure where sn X4840007 is.
2076 2014-12-09 Tonzi CO2 Probe Tree2 Profile -0.02 Location Tonzi CO2 Probe Tree2 Profile -0.02 Tonzi Tree2 profile at -2cm
2059 2014-03-27 Tonzi CO2 Probe Open Profile -0.04 Moved Tonzi CO2 Probe Tree2 Profile -0.02 This probe in the Tonzi Open profile was moved from the -4cm location to the Tree2 profile -2cm
1991 2014-01-29 Lab none Installed Tonzi CO2 Probe Open Profile -0.04 Installed at Tonzi in the Open profile at -4cm with new U-shaped tops on the PVC enclosures
1426 2014-01-27 Lab none Calibration Lab none Trueppm = Probeppm*0.9548 + -78.1; 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.
1182 2014-01-24 Tonzi CO2 Probe Open Profile -0.04 Removed Lab none Removed from Tonzi open at -4cm for lab calibration
1136 2012-02-16 Lab none Installed Tonzi CO2 Probe Open Profile -0.04 Installed at Tonzi in the Open set at -4cm
1365 2010-03-01 Lab none Calibration Lab none Trueppm = Probeppm*0.9858 + -74.43; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 383ppm, 597ppm, and 2238ppm. Ta=20.2C, P=101.9kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Jaclyn.
4632 2010-01-08 Tonzi CO2 Probe Tree1 Profile -0.04 Location Tonzi CO2 Probe Tree1 Profile -0.04 Pulled out for ambient air reading and put back.
4542 2008-03-06 Lab none Installed Tonzi CO2 Probe Open Profile -0.04 Installed in the East open grass profile at -4cm. mV and ppm readings in air were recorded before installation.
2028 2005-02-17 Tonzi CO2 Probe Tree1 Profile -0.02 Location Tonzi CO2 Probe Tree1 Profile -0.02 Location noted at Tonzi in Tree 1 (West) profile at -2cm
