Inter-comparison of High-Precision Greenhouse Gas Monitoring Instruments Across Multiple Sites in the Yangtze River Delta
摘要
Abstract
An inter-comparison experiment related to CO₂ and CH₄ was conducted at 9 atmospheric observation stations in the Yangtze River Delta of China using 2 cylinders which were traceable to the primary standard of the World Meteorological Organization's Global Atmosphere Watch(WMO/GAW).Results indicated that the precision of the observation instruments at each station could meet the quality control requirements of the WMO/GAW.However,there were systematic deviations among 9 stations,which could be calibrated using the measurement results of the comparison standard gases and work gases at each station.Based on the results of the inter-comparison experiment and the mass conservation model,we found that the deviations of the estimated atmospheric CO₂ and CH₄ content in the assumed ambient could reach to 73 tons and 0.096 tons,respectively.关键词
