Another ...... vs ....... from me

What is the definition of sky obscured? Was down to 200m vis with fog this morning (NZCH).

What is the difference between sky obscured SKOBSC and OVC, overcast 8/8ths

Cheers all

Fog, smoke, haze are all ground based phenomenon that will obscure the sky from the observer.

In other words, he can't see what the actual sky condition is because there's something obscuring his vision.

Few, scattered, broken and overcast clouds are all part of the sky condition.

Its been a while but I think it is Vertical Visibility.

Measured in Hundreds of feet

VV2= vertical visibility 200'

Correct me if I am wrong!:cool:

Yes it does. But it's not a ceiling, related to minimums. The term "broken" is.
