The effects of volcanoes and anthropogenic pollution are features of this month's issue, which begins with Maria Athanassiadou's fascinating report on a developing ability to use satellite data to track sulphur dioxide plumes emitted from volcanoes in ‘The Mt Etna SO2 eruption in December 2015 – the view from space’ on p. 273. Last year, the gas from one eruption in a relatively active period for...
UK Bonfire Night (BFN) is an annual event on 5 November which celebrates the failed ‘gunpowder plot’ of Guy Fawkes, who intended to blow up the Houses of Parliament. This event is celebrated with firework and bonfire displays, which reduce visibility and increase air pollutant concentrations. A two‐ to four‐fold increase in particulate matter concentrations was seen at some surface monitoring sites...
The SO2 plume from the eruption of Mt Etna in Sicily on 3 December 2015 crossed Asia and reached the west Pacific Ocean in 4 days. By 10 December, it had reached the Atlantic Ocean. Smaller eruptions followed, with some of the plumes travelling northwards and reaching the UK. This paper describes the plume and tracks its evolution using measurements from the IASI (Infrared Atmospheric Sounding Interferometer)...
The weather in Finland is highly variable, but the mean temperature has risen by over 2°degC from the mid‐nineteenth century to the present. The winter and spring months have especially warmed, though the large variability has been maintained. In addition, the snow season in Southern Finland is gradually shortening. Thus, heavy snowfalls in the spring are not as common as they used to be. In this...
