More greenhouse gas species with fewer instruments

Many soil gas flux systems require the use of several distinct gas analyzers to measure CO2, CH4, N2O and NH3 soil gas fluxes. However, the Eosense-Picarro system provides this full suite of important greenhouse gasses using a single analyzer, which simplifies the set-up process and reduces the number of instruments needed in the field. With Picarro’s unmatched measurement stability in the face of changing sample temperature and humidity conditions, you can be sure to capture the highest quality data set for your field measurements.

The Picarro G2508 or G2509 provide access to CO2, CH4, N2O and NH3 on a single analyzer and open up possibilities for a wider variety of research applications. Investigate plant-mediated CH4 fluxes from wetlands or rice paddies, monitor changes in CO2 fluxes from reforestation, examine drought responses of CO2 and CH4 in rainforests, or compare N2O and NH3 emissions from agricultural treatment applications – all with a single system!

Customize your automated chamber system

Our automated chambers are available in sizes ranging from 15-50 cm in diameter, as well as opaque and transparent designs. Combine transparent and opaque chambers to partition net ecosystem exchange and ecosystem respiration or pair large and small chambers to examine plant-mediated fluxes.

The larger eosAC-LT/LO chamber features two base extension options, to extend the utility of flux chamber systems by enabling measurements from larger vegetation.

Eosense chambers come equipped with internal temperature and pressure sensors to improve flux measurement accuracy. The auxiliary sensor ports allow you to add additional sensors to the system, such as soil temperature and soil moisture or PAR sensors.

Continuous monitoring of land use impacts

The Eosense-Picarro system is ideally suited for studies of land use changes and their impacts on carbon and nitrogen cycling. For example, use of fertilizers or other soil amendments can impact the GHG intensity of agricultural activities. Understanding the dynamics of gasses like N2O and NH3 are critical to increasing fertilizer use efficiency and reducing GHG emissions from agriculture while maintaining or improving crop yield.

Isotopic carbon fluxes

Isotopic CO2 fluxes can be used to determine the relative contributions of root and microbial CO2 production to total soil CO2 flux. Fluxes of isotopic CH4 can be used to differentiate biological vs geological sources of soil gas flux and examine mechanisms of CH4 production and oxidation. The Eosense-Picarro system can be used to measure isotopic CO2 and CH4 fluxes using the G2201-i analyzer.

Includes measurement scheduling and flux data processing software

The system software is designed for quick and easy scheduling and processing of flux measurements. It allows you to create custom measurement schedules, import chamber accumulation curves with a few mouse clicks, and choose between linear or exponential curve fitting to calculate fluxes. Parameters like tubing length, analyzer volume and chamber volume can be easily customized for improved accuracy and data quality. For isotopic analyzers, the software also plots Keeling curves for quantifying terrestrial and atmospheric carbon exchange processes.
