A quelques semaines seulement de l\u2019ouverture des Jeux Olympiques de P\u00e9kin, le gouvernement chinois s\u2019\u00e9vertue \u00e0 am\u00e9liorer la qualit\u00e9 de l\u2019air pendant les Jeux. Pour l\u2019aider dans sa t\u00e2che, une entreprise anglaise a fourni aux autorit\u00e9s chinoises un syst\u00e8me de contr\u00f4le de la pollution dernier cri.<\/p>\n<\/div>\n

La mauvaise qualit\u00e9 de l'air pourrait poser des probl\u00e8mes aux athl\u00e8tes olympiques, en particulier \u00e0 ceux qui pratiquent des sports de plein air tels que le cyclisme et le marathon. La pollution atmosph\u00e9rique \u00e0 P\u00e9kin \u00e9tant principalement due aux \u00e9missions des v\u00e9hicules, d'importantes restrictions de circulation ont \u00e9t\u00e9 mises en place du 20 juillet au 20 septembre. Afin de retirer de la circulation 50 % (la moiti\u00e9) des 3,5 millions de v\u00e9hicules de la ville, les v\u00e9hicules particuliers ne seront autoris\u00e9s \u00e0 circuler qu\u2019un jour sur deux. Les voitures tr\u00e8s polluantes seront interdites.<\/p>\n

L\u2019entreprise britannique CERC a install\u00e9 pour le compte de l\u2019ESA un syst\u00e8me haute r\u00e9solution de pr\u00e9vision de la qualit\u00e9 de l\u2019air \u00e0 P\u00e9kin. Celui-ci permet aux autorit\u00e9s chinoises de contr\u00f4ler les effets de ces restrictions de circulation sur la qualit\u00e9 de l\u2019air en ville. Gr\u00e2ce \u00e0 ce nouvel instrument, des pr\u00e9visions de la qualit\u00e9 de l\u2019air urbain sont effectu\u00e9es depuis le 8 juillet - exactement un mois avant la c\u00e9r\u00e9monie d\u2019ouverture des Jeux.<\/p>\n

Les pr\u00e9visions \u00e0 trois jours sont publi\u00e9es quotidiennement sur le site Internet consacr\u00e9 \u00e0 la qualit\u00e9 de l'air \u00e0 P\u00e9kin www.beijingairquality.cn<\/a> . Elles pr\u00e9sentent des cartes de pollution qui permettent de pr\u00e9voir les niveaux de dioxyde d'azote, d'ozone, de particules et de dioxyde de soufre dans toute la ville. Les utilisateurs peuvent consulter les cartes de chaque polluant s\u00e9par\u00e9ment ou l'indice de sant\u00e9 global, qui regroupe tous les polluants.<\/p>\n

Les donn\u00e9es satellite transmises par les instruments europ\u00e9ens \u00e0 bord des mission Envisat de l\u2019Esa et AURA de la NASA, viendront s\u2019ajouter prochainement pour am\u00e9liorer davantage le contr\u00f4le des \u00e9missions.<\/p>","protected":false},"excerpt":{"rendered":"
