Today provided wave induced thermals which went to the top of a heavy inversion around 5000' Later in the day the wave became stronger and the later launches got to around 9000'. With such a stable high pressure area producing a marked inversion and not helped by heather burning on the high ground, (which, incidently, could be seen on the various satellite images), the visibility was awful. The photo below shows the stark contrast in air quality at the top of the inversion.
