Abstract The clumped isotope composition (Δ47, the anomaly of the mass 47 isotopologue relative to the abundance expected from a random isotope distribution) of CO2 has been suggested as an additional tracer for gross CO2 fluxes. However, the effect

The Picarro water isotope analyzers (L2130-i/L2140-i) have become a standard technique to measure the natural abundance of δ18O, δ2H and 17O-excess of water isotopes in climate, environment, and hydrological studies. In addition, some applications

Carbon dioxide (CO2) and methane (CH4) are the most important greenhouse gases, and there is an increasing need to measure these greenhouse gases with mobile measurement devices. Picarro’s G4301 Cavity Ring-Down Spectroscopy (CRDS) analyzer is a hi

Reliable sub-ppb monitoring of reactive trace gas concentrations is essential for industrial and air quality monitoring purposes. Calibrating reactive trace gas analyzers is challenging because of the lack of certified primary standards.Here we prese

Oxygen (18O/16O) and deuterium (D/H) isotopes are a widespread tool to trace physical and chemical processes in hydrology and biogeosciences. Precision and throughput are key parameters for water isotope analysis. Here, we will present two new method

Stable isotope (δ13C and δ18O) and mole fraction measurements of CO2 are used to constrain the carbon cycle. However, the gross fluxes of the carbon cycle, especially photosynthesis and respiration, remain uncertain due to the challenging task of d

The rapidly changing global climate due to increased emission of anthropogenic greenhouse gases (GHGs) is leading to an increased occurrence of extreme weather events such as droughts, floods, and heatwaves. The three major GHGs are carbon dioxide (C
