Fig. 2

Chlorothalonil flux computed with the PTR-QI-TOF-MS inverse dispersion method (PTRMS.Inv) and the TD-GC‒MS aerodynamic gradient method (GC.AG). The inverse method was also applied at the TD-GC-MS measurements at 1.25 m height (GC.Inv) to control the field’s flux homogeneity. The top panel shows the entire period, and the bottom focuses on the first three days after chlorothalonil application. The discrepancy between the aerodynamic and inversion methods is explained by a zone near the GC mast where no pesticide was applied due to tractor manoeuvres.
