Sunshine altered temperature in shelter (6,3)
I believe the answer is:
nissen hut
'shelter' is the definition.
(Nissen hut is an example)
'sunshine altered temperature' is the wordplay.
'altered' is an anagram indicator.
'temperature' becomes 't' (abbreviation).
'sunshine' anagrammed gives 'nissenhu'.
'nissenhu'+'t'='NISSEN HUT'
'in' acts as a link.
(Other definitions for nissen hut that I've seen before include "Simple building" , "metal shelter" , "Prefabricated corrugated iron dwelling" , "Prefab" , "Corrugated iron shelter" .)
