Removed |
Lab none |
Removed from -8cm in the soil co2 profile near LiuKang's tree. This profile has not been running for a while due to a break in the power line. This style of measurements are being replaced by forced diffusion chambers. |

Calibration |
Lab none |
Trueppm = Probeppm*1.042 + -361.7; 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. |
