PANAME – Project synergy of atmospheric research in the Paris region

Abstract

<p>The Paris region (France) is increasingly the focus of urban atmospheric research. Numerous national and international research projects have chosen Europe’s largest metropolitan region as their study area to better understand and predict critical hazards (incl. heat, air pollution, thunderstorms) in the context of a changing climate. Located on rather flat terrain in continental, mid-latitude climates, the densely populated Paris region is very suitable for the evaluation of urban processes in numerical simulations at different scales. The European research infrastructures ACTRIS and ICOS are developing strategies for the improved operational monitoring of air pollution and greenhouse gas budgets, respectively. Various research projects are conducting fundamental process studies and model developments to investigate the dynamics and chemistry of the urban atmosphere and its interactions with the rural surroundings and regional-scale flow to better quantify associated health risks and inform sustainable planning.</p> <p>In addition to numerous modelling activities (chemistry-transport, numerical weather prediction, climate projections), diverse atmospheric observations are collected. These include dense surface station networks, turbulent flux towers, and ground-based atmospheric remote sensing to monitor the atmospheric boundary layer. This multi-project context motivates the pooling of resources.</p> <p>To facilitate efficient project synergy and to optimise the coordination of the individual experimental campaigns, the <strong>PANAME initiative </strong>(https://paname.aeris-data.fr/) was established. PANAME provides a framework to optimise the design of the Paris region measurement network and helps to standardise the operations. A professional, multi-disciplinary data portal is developed at the French AERIS atmospheric data centre to host the PANAME observations and model results. Here, data are collected and formatted, standardised advanced products are derived from the diverse sensor networks and high-quality visualisations are generated in near real-time. The presentation will provide an overview on the scientific objectives of the on-going projects, the deployment of measurements and simulation tools, and the data portal design.</p> <div> </div>

Modular approach to near-time data management for multi-city atmospheric environmental observation campaigns

“…This data infrastructure can be expanded as required from multiple, concurrent campaigns and projects. Most campaigns use data streams from partners instrumentation either directly or more typically from their data networks (e.g., Weather Service), or from third-party networks they contribute to (e.g., AERONET, Phenocam Network, ICOS, PANAME) (Giles et al, 2019;Richard et al, 2018;Haeffelin et al, 2023). Many of the latter are two-way contributions with campaign sensors also providing data to these networks.…”

Utility of thermal remote sensing for evaluation of a high‐resolution weather model in a city

“…Ground-based remote-sensing techniques, such as automatic lidars and ceilometers and Doppler wind lidars, allow vertical profiles to be evaluated, but they remain limited in their horizontal coverage. Dense deployment of such sensors is generally limited to campaigns lasting months to years-for example, in the urbisphere in Berlin (Fenner et al, 2022) or in PANAME in Paris (Kotthaus et al, 2023).…”
