A cloud condensation nucleus (CCN) closure experiment is carried out using data from the Chebogue Point, Nova Scotia, ground site during the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT) field experiment in 2004 ...
As a measurement, built density (coefficient of land surface to be built and total floor space) has been the object of numerous researches on urban morphology and architectural forms during the twentieth century. However, for the last ten years, its sensor ...
The scope of this paper is to provide an exptl. and modeling contribution on the role of suspended lower tropospheric particles to the UV spectral irradiance reaching the ground in urban environments. The UV spectral irradiance was measured with a UV spect ...
This work was carried out within the interdisciplinary scientific program named "Sustainable Development, Metropolisation and Pollution of Natural Resources in Ho Chi Minh-City, Vietnam". This program, launched in 1994, is financed by the Swiss National Sc ...
The determination of the sensible heat flux over urban terrain is challenging due to irregular surface geometry and surface types. To address this, in 2006–07, a major field campaign (LUCE) took place at the École Polytechnique Fédérale de Lausanne campus, ...
Increasing economic development, and growing population, generated during the last decades a very important growth of cities. Urban regions include nowadays more than half of the global population and, by 2030, this proportion is forecasted to increase to ...
A collaborative monitoring concept for developing cities. Methodological approach and realization of an urban observatory. Cities in developing countries are experiencing a considerable demographic growth. This makes their development difficult to foresee ...
The behavior and performance of four cloud condensation nucleus instruments are theoretically analyzed. They include the static diffusion cloud chamber (SDCC), the Fukuta continuous flow spectrometer (FCNS), the Hudson continuous flow spectrometer (HCNS), ...
Few borders exist which separate two countries as dramatically disparate as the Dominican Republic and Haiti. Both share the territory of the Hispaniola island, but a profound process of differentiation rooted in the colonial division of the island between ...
