                         significant regions to have measures token with instrumented 
                         aircrafts. This methodology is based on the influence functions 
                         theory, and will be used during the FIRE campaign, which will take 
                         place in the end of 2004 dry season in Mato Grosso area. At the 
                         first stage, high-resolution numeric weather forecasts will be run 
                         with BRAMS model. Before the campaign, the mean squared error 
                         (MSE) between the forecasts and the radiosonde measurements of 
                         wind velocity will be estimated. From these forecasts, considering 
                         the error, the STILT lagrangean model, which allows the 
                         time-inverted integration, will be applied. STILT will be run from 
                         the 72-hour forecast at fixed points chosen from the concentration 
                         and flux measurement sites. This model outputs a trajectory plume 
                         as well as influence functions. Preliminary sensitivity tests have 
                         been developed in order to verify how adequate this framework is 
                         to the FIRE region. A simulation over Mato Grosso in October 15th 
                         to 17th, 2002 will be presented. During this period, widespread 
                         convection was observed over the focused area. Results show that 
                         the air particles behaviour within the mixing layer and the 
                         vertical displacement due to the convective activity are well 
                         reproduced. When the MSE is considered, the influence function 
                         field becomes suggests a larger area, which is desirable when the 
                         flight over significant regions is planned.",
