Juts a quick question regaring rain radar such as the one at
http://www.raintoday.co.uk

I've noticed quite often that rain is shown above where I live in large
quantities, but on the ground many times it is just very overcast. Or
there will be heavy rain shown, but only light rain falling on the
ground.

I realise that the radar images are low resolution and can't show very
local conditions all that well, but sometimes the radar shows great
swathes of rain, and still nothing much on the ground in reality.

Is the radar merely picking up on rain in the atmosphere no matter what
the height, as opposed to actually showing rain that is reaching the
ground?

Lastly, is there a decent high resolution precipitation radar service
on the web (subscription or otherwise)?
