The urban boundary layer (UBL) is the part of the atmosphere in which most of the planet's
population now lives, and is one of the most complex and least understood microclimates …

Urban heat island (UHI) manifests as the temperature rise in built-up urban areas relative to
the surrounding rural countryside, largely because of the relatively greater proportion of …

Recent studies based on observations have shown the impact of lockdown measures taken
in various European countries to contain the Covid-19 pandemic on air quality. However …

Tropospheric trace gas and aerosol pollutants have adverse effects on health, environment
and climate. In order to quantify and mitigate such effects, a wide range of processes leading …

The purpose of this work is to study the impact of an urban land cover on local meteorology
and spatial distribution of atmospheric pollutants over the Paris region. One anticyclonic …

Multiple satellite sensors are used to analyze physical processes that determine energy
fluxes and their interaction at the urban surface. The study is based on summertime …

New developments of the international community in modeling the urban canopy surface
energy balance are presented and classified into five main categories:(i) models statistically …

This study describes and evaluates the newly developed European scale Eulerian chemistry
transport model CHIMERE-continental. The model is designed for seasonal simulations and …

Urban boundary layers (UBLs) can be highly complex due to the heterogeneous roughness
and heating of the surface, particularly at night. Due to a general lack of observations, it is …

In this paper, the “Expérience sur Site pour COntraindre les Modèles de Pollution
atmosphérique et de Transport d'Emissions”(ESCOMPTE) program is presented. The …
