Elevated atmosphere, for example, in an African country (7)
I believe the answer is:
nigeria
'an african country' is the definition.
(Nigeria is an example)
'elevated atmosphere for example in' is the wordplay.
'elevated' says the letters should be written in reverse.
'atmosphere' becomes 'air' ('air' can be a synonym of 'atmosphere').
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'air'+'eg'+'in'='airegin'
'airegin' backwards is 'NIGERIA'.
(Other definitions for nigeria that I've seen before include "Possible home for African" , "In rage I turn to this country" , "West African state" , "West African republic" , "W. African country" .)
