That will pop open a dialog box for you to enter the constraints of your subset. Use the “Refine Date Range” accordion to specify the desired date range. Use the “Spatial Subset” and “Variables” accordions to choose your lat/lon domain and variable list. Then open the “Time of Day” accordion and select all 24 hours, from 00:30 through 23:30.
