3D kinematic trajectories associated with each balloon flight have been computed using forecast RAMS output (Regional Atmospheric Modeling System). Altitude, temperature, pressure, water vapour content, liquid water content, solid water content and vertical velocity can be followed along one day backward or forward trajectories from Bauru for selected levels, for example 16 km, 18 km or 20 km.
