Opis

Le rassemblement sur la zone industrielle de FOS-BERRE d'une densite importante de mesures meteorologiques et physioo-chimiques, per- met de proposer, dans Ie cadre de notre action COST 61 a bis, l'utilisa- tion de ces mesures pour initialiser et verifier divers types de modeles. L'objectif initial de cette campagne est l'intercomparaison d'instruments de teledetection. II s'agit d'une des campagnes effectuees periodiquement, en des sites differents a l'initiative des Communautes europeennes. Ces campagnes comportent deux phases: la premiere est l'inter- calibration des instruments au m@me point, et la seconde est l'estimation des flux de polluants sur la zone etudiee. Effectuee en general a l'aide de moyens mobiles de teledetec- tion, cette estimation ne peut @tre assuree que si lion connatt Ie champ de vent et Ie profil vertical de temperature (et, bien sOr, les caracte- ristiques des sources polluantes). L'Etablissement d'Etudes et de Recherches Meteorologiques de la Meteorologie Nationale (EERM) et Ie Service Etudes et Recherches de l'E- lectricite de France (EDF) sollicites pour fournir l'assistance meteoro- logique correspondante, ont propose, du fait de la presence de moyens im- portants sur Ie site, une campagne mesometeorologique. Ce deuxieme objec- tif a permis d'obtenir des donnees tres completes, que les modelisateurs europeens devraient pouvoir utiliser. II - Aspects meteorologigues, reconstitution des champs Le site de FOS-BERRE se caracterise par sa geographie tourmen- tee: presence de la mer, de l'Etang de Berre et de reliefs. Toutefois, Ie mecanisme engendrant les fortes pollutions reste en gros Ie m@me que sur site homogene.
