Can anyone tell me whether the aviation subscription (ie £56.40ish)
version of the UKMO rainfall radar image is any larger than the free
aviation version, which seems to be just 300x283px and hence rather
small?

I know that the subscription version refreshes more often, that
Avbrief do a larger version and that even the small image probably
captures all the information that is readily available (ie assuming
that 1px might represent a 5km or 10km square). But I'd still like to
see a larger image from the UKMO if it's on offer.

Hi John,

Yes it is larger at 541x511 pixels (at least that is what doing a "properties"
on the image gives).

If you just want bigger i.e. there is no improvement in resolution, then
paste the followig code into your text editor and save as radarloop.html, or
whatever you fancy. Then just point your browser at the file, or open it in
windows explorer etc.

Does anyone know how the authentication for subscription access might
work with this? I can imagine that you have to log on initially to
your UKMO account, but how quickly does the logon time out? In other
words, do you effectively have to log on each and every time you want
to update the sequence, which would be at least a nuisance and maybe a
showstopper, or can you get away with logging in eg just once a day?

Set the browser to remember your access details and bookmark the radar page,
you can then treat it as any normal web page.
