Air pollution causes 7 million death per year globally (1/8 of total global deaths) and is now the single largest environmental health risk, particularly in megacities and other urban areas where more than half of the world's total population lives. Rapid population growth and urbanization worldwide accelerate eco-environmental/socio-economic stress as well as adverse climatic and health impacts on urban dwellers. Atmospheric modeling research has largely been performed on a horizontal grid spacing of 4-km or larger due to a lack of understanding of the local-scale phenomena, appropriate parameterizations, and adequate modeling tools and computer resources. Urban/local street level air pollution, climate change, and their impacts on population exposure and human health have increasingly received attentions by both researchers and policy makers around the world. Recognizing the urgent need for scientific advancement, pollution/exposure assessment, policy-making, and public health protection at urban/local scales, we are pleased to announce that the 2 nd Street-in-Grid (SinG) Modeling Symposium and the 3 rd SinG Model Training Workshop will be jointly held in Champs-sur-Marne, a suburb region of Paris, France during June 24-28, 2019. The SinG symposium and training workshop aim at advancing scientific understanding of local scale atmospheric phenomena, promoting state-of-the-science urban-street level modeling tools for complex interactions among urban air pollution, climate, and health, and building a high-level platform for scientists, engineers, managers, and government officials worldwide to review recent science and modeling advancement, identify research priority and direction, tackle technological and computational challenges, and provide scientific foundation for air pollution control policies and actions towards environment and human health protection. The SinG model training workshop will also provide hands-on training for a state-of-the-science SinG modeling system to students, postdoctoral researchers, and professionals.

Program Background and Agenda
Street-in-Grid model (SinG) is a new multi-scale model of urban air pollution (Kim et al., 2018) . SinG dynamically combines a 3D Eulerian chemical-transport model (Polair3D) with a street-network model, the Model of Urban Network of Intersecting Canyons and Highways ( MUNICH ). Polair3D of the Polyphemus air quality modeling platform (Mallet et
al., 2007, http://cerea.enpc.fr/polyphemus/) has been widely applied in Europe, North America, South America, Asia, and Africa (e.g., Sartelet et al., 2012; Zhang et al., 2013a, b).
MUNICH is based conceptually on the SIRANE general formulation (Soulhac et al., 2011).
MUNICH consists of two main components: the street-canyon component, which represents
the atmospheric processes in the volume of the urban canopy, and the street-intersection
component, which represents the processes in the volume of the intersection. These
components are connected to the Polair3D model at roof level and are also interconnected.
The combined model system, SinG, aims at improving urban street-level pollutant
concentrations by modeling both background and street-level concentrations at the same time.
The model development has been conducted at CEREA, France with funding from EDF
R&D and EDF R&&D China. Its first application has been realized over the Paris region. The
model is being applied over other urban areas in France, China, Brazil, and U.S.
SinG modeling symposium and training workshops have been co-organized by CEREA
and NCSU in France and China. The training covered a number of topics including the SinG
concept, the 3-D Polair3D model, the MUNICH model, as well as how to prepare input data
and set up the configurations for application using SinG. More information regarding the last
SinG model training workshops can be found at http://cerea.enpc.fr/sing-workshop and http://cerea.enpc.fr/sing-workshop-2nd.
We have engaged with two journals for publication of a special issue on "Air Quality
Research at Street-Level" jointly organized between Atmospheric Chemistry and Physics
(ACP) and Geoscientific Model Development (GMD), see GMD and ACP. All SinG symposium/training workshop participants are
highly encouraged to submit your papers to this special issue on GMD or ACP. Your paper
will be subjected to the journal's formal review and will be published in this special issue
once it is accepted.
