Clouds artist rendered innovatively (6)

I believe the answer is:

strati

'clouds' is the definition.
(stratus is a kind of cloud)

'artist rendered innovatively' is the wordplay.
'rendered innovatively' indicates anagramming the letters.
'artist' is an anagram of 'STRATI'.

(Another definition for strati that I've seen is " Grey layer clouds".)

I've seen this clue in The Guardian.
