Earth poems about the gases around the planet (10)

I believe the answer is:

atmosphere

I'm a little stuck... Click here to teach me more about this clue!

'gases around the planet' is the definition.
I can't judge whether this defines the answer.

'earth poems about' is the wordplay.
'about' indicates anagramming the letters.
'earth'+'poems'='earthpoems'
'earthpoems' anagrammed gives 'ATMOSPHERE'.

'the' is the link.

Can you help me to learn more?

(Other definitions for atmosphere that I've seen before include "Feeling" , "Feel" , "Pervading tone or mood" , "climate" , "Surrounding ambience" .)

I've seen this clue in the Sydney Morning Herald.
