Abstract

Increasing concentrations of atmospheric gases, such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), contribute to radiative forcing. Activities related to land use are importantly responsible for the buildup of CO₂, CH₄, and N₂O in the atmosphere. A survey of techniques will be described for measuring fluxes of greenhouse gases (GHG) from soils. Subsequently, sampling techniques, sample handling, and means of detection will be presented.
