摘要:Atmospheric trace gas measurements of greenhouse gases are critical in their precision and accuracy. In the past 5 years, atmospheric measurement and gas metrology communities have turned their attention to possible surface effects due to pressure and temperature variations ...

摘要:A critical issue for the long-term monitoring of atmospheric trace gases is precision and accuracy of the measurement systems employed. Both measuring and preparing reference gas mixtures for trace gases are challenging due to, for example, adsorption and desorption of the s...

摘要:Carbon dioxide and oxygen are tightly coupled in land biosphere CO2 – O2 exchange processes, whereas they are not coupled in oceanic exchange.For this reason, atmospheric oxygen measurements can be used to constrainthe global carbon cycle, especially oc...

摘要:Fossil fuel CO2 (CO2ff) is the major contributorof anthropogenic CO2 in the atmosphere, and accurate quantification isessential to better understand the carbon cycle. Since October 2012, we havebeen continuously measuring the mixing ratios of...

摘要:In order to constrain the regional flux of greenhouse gases, an automatedmeasurement system was built on an old radio tower at Beromünster,Switzerland. The measurement system has been running since November 2012 aspart of the Swiss greenhouse gases monitoring network (CarboC...
