Chamber measurements of trace gas fluxes betweenthe land surface and the atmosphere have been conducted foralmost a century. Different chamber techniques, including staticand dynamic, have been used with varying degrees of success inestimating greenhouse gases (CO2, CH4, N2O) fluxes. However,all of these have certain disadvantages which have either preventedthem from providing an adequate estimate of greenhouse gasexchange or restricted them to be used under limited conditions.Generally, chamber methods are relatively low in cost and simpleto operate. In combination with the appropriate sample allocations,chamber methods are adaptable for a wide variety of studiesfrom local to global spatial scales, and they are particularly wellsuited for in situ and laboratory-based studies. Consequently,chamber measurements will play an important role in the portfolioof the Pan-European long-term research infrastructure IntegratedCarbon Observation System. The respective working group of theIntegrated Carbon Observation System Ecosystem MonitoringStation Assembly has decided to ascertain standards and qualitychecks for automated and manual chamber systems instead ofdefining one or several standard systems provided by commercialmanufacturers in order to define minimum requirements forchamber measurements. The defined requirements and recommendationsrelated to chamber measurements are described here.
