Mesures de la température et spatialisation de l’Ilot de Chaleur Urbain à Dijon
2015
The Territorial Climate Energy Plan (PCET) of the agglomeration of Dijon (Grand Dijon) includes ameasurement campaign (6 June to 28 September 2014). 50 Hobo proV2 thermometers were deployed. The selection of siteswas carried out so that the different types of urban environment (Oke, 2006) are documented. The Urban Heat Island (UHI)is discernible mainly at night, when radiative conditions are well established the day before. It is estimated to 1°C onaverage for the summer, 3-4°C during nights of fine weather. It reached 6°C during the warmest periods of the 2014 summer.A cool axis through the agglomeration shows that vegetation and water can sensibly mitigate the ICU effect.
Urban Heat Island and air quality, Dijon, winter 2014-2015.
2016
For the 2014-2015 Winter, thetemperature patterns and the Air Quality measured over the Grand Dijon urban area are studied together.Meteorological conditions favoring the development of an Urban Heat Island (UHI) are distinguished fromthose giving rise to pollution episodes. Winter UHI are next characterized, with radiative situations followedafter the sunset by relatively strong UHI (about 3°C), and days with no insolation during which anthropogenicheat is suspected to produce a small UHI (few tenths of °C).
