Abstract
La présente invention concerne un procédé pour déterminer la position d’une source émettrice d’au moins un composé gazeux et/ou de particules dans une zone géographique, comprenant au moins une étape de mesure de la concentration en composé gazeux, de la direction et de la vitesse du vent pour différentes positions géographiques consécutives prédéfinies de manière à s’écarter d’au plus 45° par rapport à une direction instantanée ou moyenne du vent. Puis on détermine au moins un couple formé d’un minimum et d’un maximum consécutifs de la courbe et on détermine la position de la source émettrice à partir des positions du système de mesure mobile correspondant aux maxima des couples, des écarts temporels entre les maximum et minimum des couples, et de vitesses et directions moyennes du vent entre les minimum et maximum des couples.
