Lots of elevated haze swilling around to the SW of the UK on today's images,
and on the 1800z MSG3 image there is a thin line of haze extending from west
of the Bristol Channel to east Kent, similar to the one that was over
central England yesterday at dusk (see Curious Shadow thread). This can be
seen on the Chilbolton lidar as it crossed between 1730 and 1750z at a
height of between 7500 and 9100 ft. On the 0900z Larkhill ascent, and the
1200z Camborne, this is around the 'nose' at the top of the splended example
of a subsidence inversion.

Here is the Chilbolton link, but be quick as it will scroll off in an hour
or so

but can be seen at lower resolution in the 24 hour plot otherwise.

Very interesting Bernard. Even in fine weather there's always something going on.

Yes indeed and travelling across S Wales today the haze was very evident
- but I'm wondering what are the components of this haze?

Cheers

The most likely source is wild-fires in Canada.

Can't see the haze for the 8/8 cloud!! The horizon is distinct, but not as clear as it can be.
