Hello!
In the "Parameter Dictionary" indicates that all sky surface shortwave diffuse irradiance exists for the hourly time interval, but in the "data access viewer" it is not there. Please tell me how it is possible to download this parameter?

Hello @maxam to better help us find a SME or staff member to answer your question, could you please provide the name of the tool and/or dataset you are working with? Thanks -Danielle

we are talking about NASA POWER and the "all sky surface shortwave diffuse irradiance data set for an hourly interval

Hi Maxam,

The hourly "all sky surface shortwave diffuse irradiance" is not available on the NASA POWER Data Access Viewer (DAV), but it is available through the NASA POWER API service. The link below is a template you can use to get the parameter at the hourly time resolution. You will need to change the latitude and longitude for your ___location, and the start and end time.

The following link is documentation on the NASA POWER API hourly data access.
