Abstract
MUPPETS is a computer modelling tool for modelling and mapping emissions of pollutants from urban sources . It is composed of two sub-models (Figure 1): MWPET. which deals with emissions from transport. and MESS. which deals with emissions from stationary sources (anthropogenic and natural) . Both models aim to estimate spatial variations in emissions per unit area with a 1 km2 resolution . They can model a range of pollutants. subject to availability of data on emission rates from various processes . Currently. MESS contains data necessary for modelling emissions of nitrogen oxides (NOx) and volatile organic compounds (VOC) . MUPPET uses the SATURN transport model. which has built in formula to calculate emissions of carbon monoxide (CO). nitrogen oxides (NO& hydrocarbons (HC) and lead (Pb)
