You might try something like this:

openw,1,'temp'
for i=0,99 do writeu,1,output(i,*,*)
close,1
output = reform(output,3600,1800,100,/overwrite) ;reuse same memory
openr,1,'temp'
readu,1,output
close,1

Assumming output fits in memory, this should not be too bad. If you do not
have
enough memory, you will get alot of swapping during the write.
