Instrument Descriptions

CO₂ Flux Measurement Systems (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 Concentration Measurement System

This system uses an infrared gas analyzer to collect continuous measurements of atmospheric CO concentration at 60 m 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.

Automated Isotope Flask Sampler

 

Flask Sampler for Carbon Cycle Gases with NOAA ERSL

 

Aircraft Flask Sampler

This sampler is mounted in an aircraft and used to collect air samples in the free troposphere. Collection and analysis are made in cooperation with NOAA Earth System Research Laboratory (ESRL).

NOAA/ESRL analyzes gas species of CO₂, CO, CH₄, N₂O, H and SF₆. The Stable Isotope Laboratory of the Institute of Arctic and Alpine Research provides isotope analyses for ¹³CO₂ and C¹⁸OO.
