Gas sensors
Accurate, long-term atmospheric gas measurements are essential for advancing the understanding of climate processes, greenhouse gas dynamics, and atmosphere-surface interactions. These measurements demand exceptional precision, long-term stability, and confidence that data meets the strict requirements of global monitoring networks.
AtmospherIQ™ Gas Analysers from LI-COR, the new standard for atmospheric gas monitoring, exceed these requirements. Built on LI-COR’s proven Optical Feedback – Cavity Enhanced Absorption Spectroscopy (OF CEAS) platform, AtmospherIQ Gas Analysers provide continuous, high- precision measurements of key atmospheric gases.
The AtmospherIQ portfolio offers a comprehensive family of atmospheric gas analysers that address the requirements of global monitoring networks while offering consistent performance, data quality, and support.
LI8810 AtmospherIQ CH₄/CO₂/H₂O Gas Analyser: Designed for long-term atmospheric methane monitoring, the LI8810 delivers high-precision CH₄ measurements.
LI8815 AtmospherIQ CO₂/H₂O Gas Analyser: The LI8815 provides highly stable, low-drift atmospheric carbon dioxide measurements for long-term deployments.
LI8820 AtmospherIQ N₂O/H₂O Gas Analyser: The LI8820 takes precise measurements of atmospheric N₂O and delivers dependable performance for long-term monitoring stations.
Together, these atmospheric gas analysers offer research-grade precision and stability across critical greenhouse gases, helping networks and observatories meet today’s data quality expectations—and tomorrow’s challenges.
Data used by global monitoring networks must be traceable and reliable across all sites, instruments, and years of operation. Organisations such as the World Meteorological Organisation (WMO) define rigorous performance requirements that help ensure measurements support both long-term climate research and policy-relevant science.
The analysers’ technology has been independently evaluated by the ICOS Atmosphere Thematic Centre (ATC) at the Laboratoire des Sciences du Climat et de l’Environnement (LSCE) in Paris. Results demonstrate exceptional precision, drift, pressure stability, and water correction—key parameters that are needed for reliable, long-term monitoring.
Additional third-party assessments—including trials at the Atmospheric Research Station in Mace Head and evaluations by the Scripps Institution of Oceanography—further confirm the suitability of AtmospherIQ Gas Analysers for atmospheric baseline measurements.
With industry-leading performance, high precision and stability, and patented technology, AtmospherIQ Gas Analysers deliver dependable, traceable data for long-term atmospheric monitoring. Each analyser is backed by a market-leading 5-year service agreement with loan instruments and is supported by a team of dedicated application scientists.
