                            K<\/span><\/strong>evin Gurney de la Purdue University de Lafayette,Indiana, et son \u00e9quipe, dans le cadre du projet VULCAN, ont mis au point un vaste programme d’imagerie des \u00e9missions de CO2 sur l’ensemble des Etats Unis qui repr\u00e9sentent 25% des \u00e9missions mondiales.\"Vulcan12\"<\/a><\/p>\n

                   Ces travaux ont utilis\u00e9 les relev\u00e9s de 2002 des \u00e9missions de gaz \u00e0 effets de serre relev\u00e9s sur tout le territoire am\u00e9ricain par L’Environmental Protection Agency. Ils reposent sur un maillage du territoire \u00e0 l’aide d’une maille de 10X10 km<\/span><\/strong>. Les relev\u00e9s horaires \u00e0 l’int\u00e9rieur de chaque maille sont informatiquement affect\u00e9s \u00e0 des sources de CO2 identifi\u00e9es: centrale \u00e9lectrique, usine, agglom\u00e9ration, autoroute, etc. Ces traitements informatiques permettent de publier diverses cartes d\u00e9taill\u00e9es du territoire am\u00e9ricain. La premi\u00e8re carte est l’image des \u00e9missions annuelles totales de CO2 de chaque maille en logarithme des quantit\u00e9s exprim\u00e9es en tonnes de CO2. L’ensemble pour tout le territoire repr\u00e9sente 1506 millions de tonnes, pour les 1580 identifi\u00e9s par l’Energie Information Administration (les \u00e9missions par les avions par exemple ne sont pas identifi\u00e9es).<\/p>\n

                 Cette image montre d\u00e9j\u00e0 que le Sud-est des USA participe au bilan des \u00e9missions de CO2 de fa\u00e7on beaucoup plus intense qu’initialement envisag\u00e9 par des relev\u00e9s moins pr\u00e9cis. <\/p>\n

\"Vulcan23\"<\/a>               Vulcan peut publier les \u00e9missions de CO2 \u00e0 un instant donn\u00e9 d’une centrale \u00e9lectrique, d’une usine, d’une agglom\u00e9ration.<\/p>\n

                Combien serait passionnant et instructive le m\u00eame type d’image pour le territoire europ\u00e9en!<\/p>\n

                    L’objectif de ce projet est maintenant de pouvoir publier des informations actuelles, et non pas celles de 2002. Il devra \u00e9galement \u00eatre compl\u00e9mentaire des mesures de CO2 dans l’atmosph\u00e8re<\/a> r\u00e9alis\u00e9es par un satellite de la NASA \u00e0 partir de la fin de 2008.<\/p>\n
