Greenhouse Gases Monitoring Systems
Focused Photonics Inc. (FPI) champions atmospheric integrity with its precision Greenhouse Gases Monitoring Systems, harnessing advanced spectroscopy to track CO2, CH4, N2O, and other key emitters in ambient air. Our HGA series delivers continuous, high-sensitivity measurements for urban networks, industrial sites, and research stations, supporting global climate goals.
Atmospheric Audit: Principles of Greenhouse Gas Detection
Greenhouse gas monitoring employs optical spectroscopy to quantify trace concentrations by measuring molecular absorption or cavity-enhanced resonances. FPI’s systems utilize Tunable Diode Laser Absorption Spectroscopy (TDLAS) for CO2/CH4 line-specific tuning and Cavity Ring-Down Spectroscopy (CRDS) for ultra-sensitive N2O detection, achieving ppb precision without sample extraction.

Cavity Ring-Down Spectroscopy (CRDS) is a highly sensitive absorption spectroscopy technique that has developed rapidly in recent years.
Cavity Ring-Down Spectroscopy (CRDS) is a highly sensitive absorption spectroscopy technique that has developed rapidly in recent years.
Comparing to traditional method, CRDS measures the ring-down time of light within an optical cavity. This time is solely dependent on the reflectivity of the cavity mirrors and the absorption of the medium inside the cavity, making it independent of the incident light intensity.
As a result, the measurement is unaffected by fluctuations in the pulsed laser, which provides advantages such as high sensitivity, a high signal-to-noise ratio, and strong resistance to interference.
This methodology, advanced from cavity optoacoustics in the 1980s, integrates multipass cells and isotopic analyzers for flux partitioning. FPI refines it with drift-free lasers and pressure-broadening corrections, ensuring <0.1 ppm accuracy per WMO standards. In 2025’s era of enhanced transparency, our networks fuse ground sensors with satellite data (e.g., OCO-2 validation), distinguishing biogenic from anthropogenic sources to inform Paris Agreement reporting and carbon trading.
