CO2-Pro Atmosphere

CO2-Pro Atmosphere
The CO2-Pro™ Atmosphere, built on the same platform as our classic CO2-Pro™, alternates between measuring pCO2 in surface water and in overlying air.

CO2-Pro Atmosphere


For use on surface buoys or on ships for underway measurements, the CO2-Pro Atmosphere” makes both air and water measurements using the same detector, which ensures accurate real-time data for determining air-sea CO2 fluxes.

The CO2-Pro™ Atmosphere consists of 1) a NEMA box for air intake that contains separators and filters to block bulk water and aerosols; and 2) a modified version of our CO2-Pro™ instrument alternating between measuring pCO2 in the water and air. The air intake box is mounted in clean air, e.g., the top of a buoy or on a ship’s forward mast (for underway measurements).

The modified CO2-Pro™ sensor is mounted beneath a buoy, or when used in underway mode, occupies a very small space on shipboard and requires only a source of power and surface seawater. The air intake box supplies the CO2-Pro™ sensor with sample air through low permeability, UV-resistant tubing.

The CO2-Pro™ Atmosphere has the same capabilities and measurement accuracy and precision as the CO2-Pro™ sensor and allows users to determine CO2 fluxes in and out of the oceans.
