Assuming your data is stored in table format, say T, the following code can do that.
func = @(x) T(T.aod == min(x),:);
Tout = splitapply(func,T.aod,findgroups(T.doy));
The result is like this:
>> Tout
Tout =
3×3 table
doy time aod
___ ________ _____
5 05:47:07 0.616
7 06:47:16 0.532
11 08:31:57 0.626
