Specific tasks and responsibilities:

• Contributing to the work of the Steering Committee of the EU-funded pilot project in identifying needed locations for use in the monitoring of gases controlled under the Montreal Protocol.
• Using existing simulations, assess the feasibility of using identified locations for monitoring controlled gases under the Montreal Protocol. These locations will be fewer than ten and will be proposed by the Steering Committee.
• Carry out sub-sampling of existing high-frequency data from Advanced Global Atmospheric Gases Experiment (AGAGE) stations to mimic obtaining various frequencies and time of flask sampling from the same sites; compare the modelled emissions fluxes, mapping and uncertainties based on the sub-sampled measurements with those based on the full high-frequency measurement data; document the work through clear and concise reporting including recommendations for next steps.
• Prepare a final report based on the assigned tasks, including the key outcomes and pertinent recommendations for future work.
• Consult effectively with the Steering Committee and other scientists involved in the project to assist in the development of a robust approach to implement the tasks assigned. Of particular interest to the Steering Committee is the use of the subsampled modelling results for cost/benefit analyses of flask sampling at various frequencies compared to high-frequency in-situ measurements in future locations of sampling stations.

• Extended knowledge in the area of ozone layer protection and climate change and relevant atmospheric physical and chemical processes with particular emphasis on quantification of emissions is required.
• Demonstrated expertise in atmospheric modelling with proven ability to develop and implement inversion techniques to estimate concentrations and emissions of ozone-depleting and/or greenhouse gases from atmospheric observations is required.
• Demonstrated ability to develop and validate modeling methodologies, analyze atmospheric data, apply emissions quantification techniques, and integrate multiple data sources for comprehensive analyses is required.
