Thesis Summary In this study' the sourcesofambient aerosolsin th€ uÍbanatmosphereofPrague, Czech Republic are apportionedusing bilinear Positive Matrix Faďorization (PMF2). Prior to this worl limited use of PMF techniquehas b€ťÍ' ryplied to Prague aerosols while elsewherearoundthe world, it has beenaaively usedby aerosol scientiststo reap thebenefitsince its fint inÚoduction in tbevea 1993. ln the currentstudy,the combinď pctrte nmber size disributions and readily available gaseous concentration .láa $tÍE 'E.d b ryortioning winter sub.micron particle sources in the urbm atmospbc of hgr.
