Resumen:
The SALLJEX experiment was held during the summer 2002-2003. It consisted of the three-dimensional observation of the atmosphere to study the structure of the low level jet. Daily precipitation water samples were collected at two stations (Resistencia and Salta) in northern Argentina, and the isotope content was analyzed. These data were used to verify the trajectories obtained from a 3-D kinematic model (3D-MTC) developed by the University of Sao Paulo, Brazil. Values of deuterium excess were related with air masses of continental origin, whilst low values were associated with air masses with longer oceanic trajectories. Furthermore, although data are scarce, results show that oxygen-18 and deuterium excess in rainwater are related with the occurrence of the low level jet
