ABL monitoring campaign PARIS

The Paris Region will host three field campaigns in summer 2022 (June-July) that will focus on the study of physical and chemical processes in the urban boundary layer using innovative observations and modelling.

• The ACROSS project is designed to improve the understanding of mixing effects of urban and biogenic air masses on the oxidation of tropospheric VOCs and of the resulting properties of the products.
• The sTREET project will study the impact of stress on urban trees and on city air quality through characterization of biological VOC emissions, physiology of trees submitted to water stress and VOC / aerosol air composition.
• H2C (Heat and Health in Cities) will study the impact of exposure to heat and atmospheric pollutants on human health, and will evaluate high resolution numerical simulation models that enable more precise mapping of exposure.

These project take place in a context of a WMO research demonstration project ahead of the 2024 Paris Olympics focusing on future Meteorological Forecasting systems at 100m (or finer) resolution for urban areas.

All three projects rely on precise in-situ measurements of atmospheric chemical composition, but a significant network of boundary layer profilers will be deployed. These include ALCs for aerosol and cloud profiling as well as monitoring of ABL heights, MWRs for temperature and humidity profiling, and DWLs for wind and turbulence profiling. Several international partners have shown interest in participating in these projects. We are currently finalizing the design of the urban remote sensing network and are considering additional contributions.

We invite everyone interested in the Paris 2022 activities to join this interactive SWG. It will be a great opportunity to promote the advanced products provided by PROBE and to engage with various users (modelling of weather, air quality, health).

Especially for ECI – there will be training opportunities available to those who would like to engage in measurements and data analysis (with travel support opportunities)!
