Exercise

Daily hours of clear sky

In a previous exercise, you analyzed the 'sky_condition' column to explore the difference in temperature on sunny days compared to overcast days. Recall that a 'sky_condition' of 'CLR' represents a sunny day. In this exercise, you will explore sunny days in greater detail. Specifically, you will use a box plot to visualize the fraction of days that are sunny.

The 'sky_condition' column is recorded hourly. Your job is to resample this column appropriately such that you can extract the number of sunny hours in a day and the number of total hours. Then, you can divide the number of sunny hours by the number of total hours, and generate a box plot of the resulting fraction.

As before, df_clean is available for you in the workspace.

  • Get the cases in df_clean where the sky is clear. That is, when 'sky_condition' equals 'CLR', assigning the result to is_sky_clear.
  • Resample is_sky_clear by day, assigning to resampled.
