Abstract
In this work, the time evolution of <sup>36</sup>Cl concentration and <sup>36</sup>Cl/Cl isotopic ratio has been studied in rainwater samples from Seville, Southern Spain. <sup>36</sup>Cl concentrations range between 10<sup>5</sup> – 10<sup>7</sup> at l<sup>−1</sup> and <sup>36</sup>Cl/Cl ratios range between 10<sup>−15</sup>–10<sup>−13</sup>, in good agreement with other values found in literature. The time evolution of these values suggests that <sup>36</sup>Cl is more available in late spring due to the injection of stratospheric air into the troposphere. The arrival of stable chlorine coming from the Atlantic Ocean also seems to have an important influence on the <sup>36</sup>Cl/Cl isotopic ratio. Finally, the values obtained for the <sup>36</sup>Cl deposition are noticeably higher than the values predicted by cosmogenic production models. This fact has been found by other authors.
