Verification of non-CO2 greenhouse gas emissions of Europe; capabilities of the current and future surface network
Thursday, 18 December 2014: 8:45 AM
In this talk we will present the latest results of the InGOS project. The unique European surface network of high precision observations of non-CO2 greenhouse gases started in the 1990's and is still growing. In the EU FP7 InGOS project (http://www.ingos-infrastructure.eu) we integrated the rather heterogeneous network of more than 20 stations and gathered improved homogeneous datasets of the historic data including analysis of random and systematic measurement errors. This dataset will be used in an ensemble inversion exercise of at least 5 different state of the art atmospheric inversion setups for CH4 and N2O. Special attention has been given to quantify the transport errors of the underlaying atmospheric transport models through comparisons between te models and with observations of 222Rn tracer and boundary layer depths. We will test our target that the future or even the current network allows us to determine the European net emissions on country scale and at yearly time scales at a precision better than that of the bottom-up inventories.
