Thematic Session Proposal for the 3rd joint session of the EMEP SB/WGE 11-15 September 2017 Thomas Dirnböck (on behalf of WGE chair and vice chairs) Joint Meeting of the Extended Bureaux EMEP-SB and WGE 20-23 March 2017

Thematic Sessions To streamline the cooperation between EMEP and the WGE on the most important and emerging issues Thematic session 2016: Interaction between air pollution and climate change; Benzo(a)Pyrene; Ozone Issues Thematic session 2017 (Monitoring) Improving the interaction between ecosystem monitoring and modelling to better inform the WGSR and the EB about trends and impacts of air pollution

Objectives Review of the LRTAP monitoring network in order to Identify the strengths and weaknesses of the network Identify data gaps Regarding empirical evidence of air pollution effects Regarding its usefulness for modelling (effects/impacts) Regarding new challenges (e.g. N dry deposition, P in waters, climate change..) Identify common and complementary data Review reporting data (ECE/EB.AIR/WG.1/2008/16/Rev.1)

Questions Do we have the right data to support the WGSR and EB? Air pollution impacts/recovery, dose-response, „new“ issues such as biodiversity; interactions of air pollutants with climate change; for running models; … How can we integrate and improve our monitoring network Cooperation between ICPs and Centres; between monitoring and modelling (CCE, JEG-DynMod); between WGE and EMEP in general; … How can we increase the participation of countries and the density of monitoring sites? Should we prioritize monitoring? To address the most important policy questions; to deal with decreasing funding

Target Groups And TFs and Centres for modelling The focus is on TFs and Centres which follow an ecosystem approach ICP-Waters ICP-Forests ICP-Integrated Monitoring And TFs and Centres for modelling WGE: ICP Modelling and Mapping, the CCE, and JEG EMEP: particularly MSC-W

Proposed content for presentation in Sep.-Meeting Description of the monitoring network sites, geographical distribution, sampling frequency, representativeness Purpose of the network eutrophication, acidification, biodiversity, air quality monitoring, outlook to the future, etc. Environmental compartments of interest atmosphere, soil/soil-solution, waters, biota, cross-cutting, etc.

Proposed content for presentation in Sep.-Meeting Key datasets data management, data availability, usefulness for modelling, data reporting (according to guidelines ECE/EB.AIR/WG.1/2008/16/Rev.1) Key gaps (critical review) In monitoring of effects In the provision of model inputs Collaborations between TFs and Centres Existing cooperations and outlook to the future
