The LI-7500A is an excellent choice for scientists who wish to measure CO2 and H2O flux and density over many environments, including natural and agricultural ecosystems, urban areas, and water bodies. Ecosystems commonly measured include grasslands, deciduous forests, tropical environments, scrublands, deserts, wetlands, and others.

Wetlands:
In wetland ecosystems, where access to mains power is often limited, the low power and low maintenance features of the LI-7500A make it an obvious choice for CO2/H2O density measurements.

Urban Flux:
Urban environments occupy a significant and growing portion of Earth's surface. CO2/H2O flux from urban ecosystems cannot be ignored. The LI-7500A is ideally suited for these applications with its excellent stability and undampened measurements.

Aircraft Eddy Covariance:
Scientists have mounted the LI-7500 to fixed wing and rotary-wing aircraft and successfully measured CO2 and H2O flux. Be sure to check FAA guidelines before attempting this kind of measurement.


Agro-ecosystem Flux:
Agricultural ecosystem flux varies with crop type, management regime, season, region, and many other variables. The long term stability and low power requirements make the LI-7500A an ideal instrument for these applications.

CO2/H2O Flux over Water Bodies:
Lakes, tidal zones, seas, and oceans are very relevant to the global carbon cycle. The LI-7500 is used on stationary platforms, buoys, and boats to measure CO2 and H2O flux in these environments. The low power demands and relative insensitivity to vibration make the LI-7500A an ideal instrument for these applications.

Carbon Capture and Sequestration:
The eddy covariance method is an effective way to monitor large areas where CO2 may escape from the subsurface. Before attempting to detect a leak from an underground storage location, the baseline CO2 flux must be established. The LI-7500A is an excellent instrument for all stages of CCS monitoring — including pre-injection, injection, and post-injection phases.
