Sorry Dave. The ceiliometer records down to the nearest 100ft, so when
we currently have 299ft (being a bit extreme to make a point) cloud
ceiling it is recorded as 200ft OVC002. When it is 180 ft it is recorded
as 100ft OVC001. So the change is from 1 foot to 100feet.

Ah, that makes sense. Thanks for the succinct explanation.
