3.2) Falcon flight downwind of Tuzla (Bosnia)
•
Mass balance for rectangle (in red) to calculate instantaneous SO2 flux [kg s-1]
Airborne measurements grouped into bins of 300 x 100 m (horiz. x vert.), interpolated
between flight legs, lowest flight leg valid down to ground
F
=
7(0, 2) sin(a) (C(0, 2) - Cbg)L dēdz,
ppb to g m²³ by ideal gas law; integrated in horizontal and vertical; L=difference
between two points on regular grid of 300x100 m, U=wind speed, a-wind angle
Interpolated measurements along red line: from north to east, south and west
