Post #4: Yearly Averages

In the previous blog, graphs of the monthly averages for temperature and precipitation for Portland were shown. This entry includes yearly averages of the high and low temperatures as well as the average temperature and annual precipitation.

The data shown covers from 1941 to 2012. The original data had high and low temperatures as well as the precipitation recorded as daily values. The average of all of these values was taken to derive the yearly average for the temperatures. For precipitation, all of the values were added together to derive the annual value. It should be noted that the original data also had partial data for the year 1940 and 2013. Because this data was only partial, it was excluded from the yearly average because the results were unreasonable outliers.
