Influence of Meteorological Variables in NOx Pollution

Abstract

This work shows to the results of a study of the existing relation between different meteorological variables and the measured concentration of NOx in downtown of Rosario.
The meteorological variables were temperature, wind, atmospheric pressure, pluvial precipitation and ambient air humidity.
The results show that the nitrogen oxide concentrations are fallen as the different meteorological variables increase their absolute values, being of negative sign all the obtained coefficients of correlation for each one of the variables.
One concludes that when the atmospheric temperature average increases, the concentration is smaller. For majors precipitations, minors are expected concentrations. For high wind speed, smaller concentrations are. For the pressure, the theory does not establish anything, but it is understood that the days of low pressure indicate precipitation possibilities, thus the obtained results are consistent because when increasing the pressure are no precipitations. For the humidity a relation could not be established.
