The curious looking device on a well weighed down tripod seen here on the roof of a house's garage is part of a network of pollution monitoring stations placed in various strategic locations around Swansea. More information and recent data from this and other monitoring stations can be found at http://test.swansea.airqualitydata.com/cgi-bin/dustsites.cgi . The picture was taken on the M4 motorway - a pileup just ahead had closed the road and was being cleared to the hard shoulder at the time the picture was taken.
