Wind averaging duration for "10m u-component of wind"?

Hello folks,

I'm using the dataset "ERA5 hourly data on single levels from 1979 to present", specifically the "10m u-component of wind" (and v-component).

I'm wondering, what is the wind averaging duration for "10m u-component of wind"? Is it 10-minute wind or 1-hour wind?

I specifically need to use 10-minute wind. So if the "10m u-component of wind" is 1-hour wind, I may need to apply a factor to convert the "10m u-component of wind" to 10-min wind.

I looked through the documents/references, but did not find a specific explanation on the averaging duration.

Any help is appreciated!

Thanks!

Jim
