- Five year average frequencies were plotted around the mean for the full-time period.

- First COOP stations with less than 10% missing daily precipitation for the period 1895-2011 were identified. - For each station, the number of events in each year exceeding the threshold was computed. - Next, grid box (1 degree latitude by 1 degree longitude) average values were calculated each year, by averaging the values for each station available in the grid box. -The annual grid box values were used to produce a state value by averaging the values for all gird boxes containing state station date. - Then the annual mean number of days in the state was calculated for the full time period, as well as the annual mean number of days for each five-year period.

The duration of this activity was 15 minutes.
