POWER

Good day! There is no information on the NASA POWER website on the average monthly percentage of the time when the wind speed at an altitude of 50 m above the Earth's surface is within the specified range (%).
Is there access to this information?

The "POWER GLOBAL" chapter has information on wind speed at 10 meters
Is there such information for a height of 50 meters in one file or only for "Power single point"?

Hello, the POWER project does not specifically provide a data parameter where the monthly percentage of the time wind speed is within a specified range. The POWER Application Programing Interface (API) provides Wind Speed at 2, 10, and 50 meters at the Hourly, Daily, Monthly, and Climatology levels. You are able to compute the data parameter that you are looking for by downloading Daily data summing the total number of days and then summing the number of days the meet your selection criteria. Once you divide the two numbers you have a percentage overall; the same methodology can be applied of a month.

POWER also provides custom wind speeds based on surface types and a pre-computed wind rose datasheet.

Thank you,

Thanks for the answer.
Can you please tell me if the POWER GLOBAL widget has information about the average wind speed at an altitude of 50 meters for the climatological level? At the moment, the information there is only available for 10 meters.

No problem at all.

Currently the POWER Data Access Viewer (DAV) only includes wind data at 2 and 10 meters but the POWER API will allow users to access wind data at 50 meters.
