I want to find what is the maximum, minimum rainfall for 30 min, 1 hour etc. but simple hourly sum (that is adding and finding sum of time 01:00 to 02:00) is not enough.
As I want to find maximum and minimum from all possible combinations of the desired duration (that is for above hourly maximum case, I also want to look at max from 0110 to 0210, 0130 to 0230 etc) please help
thanks
