UK greenhouse gas leak detected from space

A thinner cloud might not prevent all the light getting through, and of course as clouds come in many shapes and are normally moving, the position on the ground being blocked varies too. But in general yes, even thinner clouds affect the data. The best remote sensing data will usually be taken on a cloudless day. Unless, of course, the whole point is to look at clouds and get data from them. But in this case, they're looking at gas leaks on the Earth, so the clouds are only getting in the way.

No problem - Earth observation is kind of my thing, but I appreciate that it requires explaining.

I'd be interested in their findings. & maybe they can find ways it doesn't take 3 months.
