Abstract:
In this report an atmospheric transport model (the RIVM/KNMI PUFF- model) is described. The model is intended for operational use at KNMI and RIVM in case of an accidental release of (toxic or radioactive) gases or particles into the atmosphere. In its operational version the model area will cover most of Europe. The main processes accounted for in the model are: relative diffusion by wind shear and turbulence, advection as a function of space and time, the diurnal cycle of boundary layer height and stability, dry and wet deposition and linear chemical transformation or radioactive decay. Input fields for the model are: horizontal wind (depending on the numerical weather prediction model every 3 or 6 hours on 2 or 3 levels), precipitation data (every 3 hours, optional) and the height of the mixed layer (every 3 hours, optional). The meteorological data used may be either analyses or prognostic fields. The use of prognoses offers the possibility to create a medium range (0-72h) air quality forecast. The source is defined by an effective emission height and a source strength as a function of time. The model calculates fields of concentrations near the surface and dry and wet depositions as a function of time.<br>
