Z_b	initial meters above sea level (m).
X_e	final x coordinates.
Y_e	final y coordinates.
Z_e	final meters above sea level (m).
dCL	offset distance for each source relative to the centerline.
sigmaz0	vertical dispersion (m).
lanes	number of lanes at each street.
Emis	Column with the emissions whose unit must be g/ms.
Hw1	Height of the barrier 1 (m).
dw1	Distance to barrier 1 (m).
Hw2	height of the barrier 2 (m).
dw2	Distance to barrier 2 (m).
