Evidence of traffic-generated air pollution in Havana

François Golay, Alain Clappier, Jessie Madrazo Bacallao

In Havana, transport is blamed as a likely source of pollution issues. which is usually supported on arguments referring to a vehicle fleet mainly made of old cars (i.e., most models are American from the 1950s or Russian from the 1980s) with poor technica ...

Multi-scale modeling of the urban meteorology: Integration of a new canopy model in the WRF model

Dasaraden Mauree, Alain Clappier

Urban parametrizations have been recently developed and integrated in mesoscale meteorological models for a better reproduction of urban heat islands and to compute building energy consumption. The objective of the present study is to evaluate the value of ...

On the Coherence in the Boundary Layer: Development of a Canopy Interface Model

Dasaraden Mauree, Alain Clappier

A 1D Canopy Interface Model (CIM) is developed to act as an interface between a meso-scale and a micro-scale atmospheric model and to better resolve the surface turbulent fluxes in the urban canopy layer. A new discretisation is proposed to solve the TKE e ...

An evaluation of the estimation of road traffic emission factors from tracer studies

Alain Clappier, Luis Carlos Belalcazar Ceron

Road traffic emission factors (EFs) are one of the main sources of uncertainties in emission inventories; it is necessary to develop methods to reduce these uncertainties to manage air quality more efficiently. Recently an alternative method has been propo ...

A new building energy model coupled with an urban canopy parameterization for urban climate simulations-part I. formulation, verification, and sensitivity analysis of the model

Alain Clappier, Andrea Krpo

The generation of heat in buildings, and the way this heat is exchanged with the exterior, plays an important role in urban climate. To analyze the impact on urban climate of a change in the urban structure, it is necessary to build and use a model capable ...

Estimation of road traffic emission factors from a long term tracer study

Alain Clappier, Luis Carlos Belalcazar Ceron, Erika Maria Zarate Torres, Minh Dung Ho

Road traffic emissions, one of the largest source categories in megacity inventories, are highly uncertain. It is essential to develop methodologies to reduce these uncertainties to manage air quality more effectively. In this paper, we propose a methodolo ...

Towards improving the simulation of meteorological fields in urban areas through updated/advanced surface fluxes description

Alain Clappier

The increased resolution of numerical weather prediction models allows nowadays addressing more realistically urban meteorology and air pollution processes. This has triggered new interest in modelling and describing experimentally the specific features an ...
