All the listed wind measurements are available in the APIs and CSV reports, but only the 10-minute values are displayed in the UI without the standard deviation values.

For the rain and hail duration and accumulation, note the following differences in the CSV reports:

In the 1-h averaging CSV report, the 10-minute sum is an average of the 10-minute sum values during the 1-hour averaging period. The 60-minute and 24-hour sums are shown as maximum values.
In the 6-h and 24-h averaging CSV reports, the 10-minute and 60-minute sums are averages of the sum values during the averaging period. The 24-hour sum is shown as maximum value.

The CSV reports provide the values in the units and time zone as selected in user preferences, but the 24-hour cumulative sum is always reset at UTC ±00:00.
