对陆地表面和大气之间的微量气体通量进行室测量已经进行了近一个世纪。不同的室技术，包括静态和动态，在估算温室气体（CO2、CH4、N2O）通量方面已取得不同程度的成功。然而，所有这些都具有某些缺点，这些缺点要么阻止它们提供对温室气体交换的充分估计，要么限制它们在有限的条件下使用。一般来说，室法成本相对较低且操作简单。与适当的样本分配相结合，腔室方法适用于从局部到全球空间尺度的各种研究，并且特别适合原位和实验室研究。因此，暗室测量将在泛欧长期研究基础设施综合碳观测系统的组合中发挥重要作用。综合碳观测系统生态系统监测站大会各自的工作组已决定确定自动和手动室系统的标准和质量检查，而不是定义商业制造商提供的一个或多个标准系统，以确定室测量的最低要求。此处描述了与室测量相关的规定要求和建议。
Chamber measurements of trace gas fluxes between the land surface and the atmosphere have been conducted for almost a century. Different chamber techniques, including static and dynamic, have been used with varying degrees of success in estimating greenhouse gases (CO2, CH4, N2O) fluxes. However, all of these have certain disadvantages which have either prevented them from providing an adequate estimate of greenhouse gas exchange or restricted them to be used under limited conditions. Generally, chamber methods are relatively low in cost and simple to operate. In combination with the appropriate sample allocations, chamber methods are adaptable for a wide variety of studies from local to global spatial scales, and they are particularly well suited for in situ and laboratory-based studies. Consequently, chamber measurements will play an important role in the portfolio of the Pan-European long-term research infrastructure Integrated Carbon Observation System. The respective working group of the Integrated Carbon Observation System Ecosystem Monitoring Station Assembly has decided to ascertain standards and quality checks for automated and manual chamber systems instead of defining one or several standard systems provided by commercial manufacturers in order to define minimum requirements for chamber measurements. The defined requirements and recommendations related to chamber measurements are described here.
