1. Cylindrical method of quantifying fugitive emission rates from pollution sources comprising:

  • A. driving a pollutant sensor in a peripheral arc surrounding a pollution source;

    B. gauging wind velocity and direction at an index point downwind of the pollution source;

    C. advancing said pollutant sensor to said index point;

    D. outlining at said index point an arcuate pollution detection plane, said plane being oriented transversely and vertically with respect to the wind;

    E. sensing pollutant concentration at a series of height intervals within the vertical and lateral confines of said arcuate pollution detection plane, so as to obtain integrated products of cross wind concentration and wind speed; and

    F. displaying said products as a vertical profile of total mass flux of pollutant through said detection plane.
