Resumen
This article proposes a protocol for the simultaneous determination of the position, release time and mass release rate of an unknown gas emission source from experimental data in the form of an inverse problem, since these are the main variables in the short duration release of pollutants.
Records of pollutant concentration and of measurement time (with their inherent errors) carried out at two measuring stations are the input data for the inverse problem. The actions of the protocol are divided into two well-differentiated stages. In the first, the simulations are started for each iteration, the functionals are calculated to program the next iteration, setting the new values of measurement time and the distance of the emission source in downwind direction with respect to the measuring stations by comparing the simulated and experimental values, and so on until reaching the final solution. In the second, an analogous procedure is followed until the mass rate and the emission source ...
