Model 1. Exposure to spray drift - Boom Spraying‌ 7.1.1 Model outline& conceptual model‌ A diagram of the conceptual model for the spray drift component, which describes the source and dispersion, is shown in Fig.1. The Silsoe Spray Drift Model (▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇▇▇, 2010) is a particle tracking model, which simulates the release of droplets from a moving boom and calculates their trajectory, subject to complex air flows close to the nozzle, and then assumes a random walk further away. This model was used to generate training runs across the range of input variables, from which a series of emulators is developed. A separate emulator was developed for each model output, and for each non-continuous variable. Model outputs are 1. Ground deposits 2. Airborne spray (adult) 3. Airborne spray (child) 4. Inhalation factor (adult) 5. Inhalation factor (child) The non-continuous, or categorical, variables are 1. Spray quality (fine, medium, coarse, very coarse) 2. Crop height (short crop/bare soil, defined as 0.1 m; 0.5 m; 1.0 m; 1.
