The featured chart presents the number of times a given daily temperature or precipitation record was either set or tied for Ames. The algorithm used for this plot established the daily records in 1893 and then counted how many times that baseline record was tied or bested for each day of the year. The overall chart average is around 4 days, which means that a daily record is tied or bested during four years of the period since 1894. There are some interesting artifacts in the plot, like the 11 day value in January for low temperature and the low numbers for high temperature in July as the records were set very high during the 1930s and not bested since.
