This article reports measurements of column densities of trace gas concentrations within the polar vortex by means of an FTIR instrument using moon light as a light source. N[sub 2]O, CH[sub 4], HF, HCl, O[sub 3], NO[sub 2], HNO[sub 3], and ClONO[sub 2] were measured, and correlated with the observation of polar stratospheric clouds, which appeared at several times during the observation period.
