Noctilucent Clouds (NLCs) are a seasonal wonder of the natural world. They are confined to the midsummer months, when they can be seen glowing out of the twilight during the hours of dawn and dusk.
Their name implies that they are "night-shining". This feature is a result of their extremely-high altitude, where the atmosphere-proper is giving way to the near-Earth space environment. They remain sunlit long after regular clouds have disappeared into darkness.
This talk will look at what NLCs (and observations made by the NERC MST Radar near Aberystwyth) can tell us about this remote region of the atmosphere.
Tea will be provided from 5.15 p.m. in the Staff Common Room, Floor 2, Physical Sciences Building.
All are cordially invited to attend.
