- CO2 Flux Measurement System (SGP)
These systems measure wind velocity and direction, temperature, and CO2 and H2O densities via an infrared gas analyzer, and then calculate estimates of CO2 and H2O fluxes on varying time scales from 0.5 to 4.0 hours.
- Precision Gas System
This system uses an infrared gas analyzer to take continuous, precise measurements of CO2 at heights of 2, 4, 25 and 60 m above the ground.
- CO COncetration Measurement System
This system uses an infrared gas analyzer to collect continuous measurements of atmospheric CO concentration at 60m above the ground.
- Radon-222 Concentration Measurement System
In November 2006, we started to monitor atmospheric radon-222 concentrations at 60 m above the ground.
