nca4-se_change-in-hot-days-warm-nights_23k9l-process

Methodology:

1. Stations were chosen with less than 10% missing data for the period of 1895-2011

2. For each station, the number of days with maximum temperature above 95F was counted for each year.

3. For each one-degree by one-degree grid box in the southeast region, for each year with available data, the average number of days above 95F was calculated as the arithmetic average of the values for all available stations in the grid box.

4. The average number of days above 95F in the region was calculated as the arithmetic average of all of the grid box values in the region.

5. The decadal values were calculated as the average of the annual values in each decade.

The decadal averages were plotted as a bar graph
