All 731 daily weather codes equal rounded hourly means in UCI Bike Sharing for 2011–2012
We checked the hourly and daily UCI Bike Sharing files for 2011–2012. All 731 daily weather codes equal the mean of the observed hourly codes, rounded to the nearest integer with halves rounded up. This match does not prove the provider's processing method. Hourly codes 3 and 4 mark broad precipitation classes. At least one such hour occurs on 300 dates, but only 21 dates have daily code 3. Daily code 1 includes 87 dates with such hours. Daily code 3 covers 22.4% of all recorded precipitation-class hours. The distinction persists on the 655 dates with all 24 hour labels. We give exact bounds for each daily code and a 731-row table that keeps hourly class counts and observed denominators. Raw rental-count ratios differ between weather definitions because they compare different date groups. They are not causal effects. A separate parser and a full repeat confirm the results. The package preserves source data, hashes, code, figures and repeat instructions.

This is the required source study for the UCI data. We read its abstract and metadata; full subscription text was not available.

This earlier study uses the hourly source file and checks daily rental sums and absent hour labels. We reuse the same retained source ZIP and add an audit of daily weather codes.
