Ozone signatures of climate patterns over the Euro‐Atlantic sector in the spring
Abstract The influence of low‐frequency tropospheric dynamics upon column ozone interannual variability is estimated in the spring season over the Euro‐Atlantic sector. This dynamical variability of tropospheric origin is examined in terms of leading climate patterns, derived from an empirical ortho...

Abstract The influence of low‐frequency tropospheric dynamics upon column ozone interannual variability is estimated in the spring season over the Euro‐Atlantic sector.
