Survey carried out for atmospheric environmental monitoring

In order to achieve the target of national ‘12th Five-year Plan’ (2010~2015), to implement practical metrology plans of atmospheric environmental monitoring, to support our national green house gas emissions mitigation and to improve service abilities, Gas Lab of the Division of Themophysics and Process Measuremnents conducted a survey of atmospheric environmental monitoring and green house gas emissions this autumn. More than ten scientists from Gas Lab together with institute/division leaders joined in this activity.

On August 14th, they surveyed Institute of Atmospheric Physics, Chinese Academy of Sciences. They then surveyed Beijing Municipal Environmental Monitoring Center. On August 30th, they surveyed Key Laboratory for Atmospheric Chemistry of Chinese Academy of Metrological Sciences. In this survey, scientists from different institutes exchange opinions and experiences on methods of atmospheric environmental monitoring, reference material of gas components for practical use and calibration of instruments used for atmospheric environmental monitoring. The common viewpoints, which they shared, included: accuracy of atmospheric environmental monitoring should be based on high quality reference materials; we should establish more types of green house gas CRMs, for example, volatile organic compounds; for some components, the uncertainty of green house gas CRMs should be better than 0.1% to satisfy the requirement of monitoring as little change of atmospheric components as possible; scientists from different fields should joint together to decrease green house gas emission, improve air quality and face up to climate change. On September 3rd and 4th, they attended a workshop between NIM and NIST, USA, on Measurements and Standards for Climate Change. In the meeting, the scientists from the two counties thoroughly discussed about their technique and method on preparation of green house gas standards.    

According to this survey, Gas Lab proposed some new research projects, for example, High Quality Green House Gas Reference Materials in Real Air Matrix; research on Gas Isotope Reference Materials; The Study of CRDS As Potential Primary Method; Zero Air Reference Materials; Multi-Component Volatile Organic Compounds Reference Materials With PPB Concentration Level in Cylinder, etc.
