A new study report compares six different technologies for measurements of greenhouse gases (GHGs) from the soil. In\u00a0recent\u00a0decades, several technologies have been developed to measure GHG concentrations and fluxes. For the first time, 6\u00a0devices using different measurement technologies were compared in the test measurements at CzechGlobe, the Global Change Research Institute in Brno, Czech Republic.<\/p>\n

Technologies and devices used:<\/strong><\/h2>\n
    \n
  • Two gas chromatographic systems with a barrier discharge ionization detector (GC-BID) and an electron capture detector (GC-ECD)<\/li>\n
  • Portable GHG analyzer based on laser absorption<\/li>\n
  • Photoacoustic field gas analyzer equipped with a dew point controller, and<\/li>\n
  • Two portable Fourier transform infrared (FTIR) devices<\/li>\n<\/ul>\n

    These devices and measurement methods were\u00a0evaluated and compared by conducting experiments to measure absolute concentrations of GHGs (CO2, CH4 and N2O), as well as the fluxes of CO2 from artificial soils.<\/p>\n
