Erratum to “Influence of Stratospheric Intrusion on the Surface Ozone Levels in India”

(1) “The PV value was >1.6 and RH at the tropopause were low (20%), indicating the presence of air masses having stratospheric origin,” in page 3, column 2, 4th last line, should be changed to “The PV value at the tropopause was >1.6 and RH at 300 hPa pressure level was low (20%), indicating the presence of air masses having stratospheric origin.”

(2) In pages 4-5 in Figures 4(a)–4(i), (a, b, c, d, e, f, g, h, and i) mentioned inside the figures have been removed.
