Reports for each day are put onto a grid 80 km x 80 km. 2. If one or more reports occur in a grid box, that box is assigned the value "1" for the day. If no reports occur, it's a zero. 3. The raw frequency for each day at each grid location is found for the period (number of "1" values divided by number of years) to get a raw annual cycle.
