Air Density Elevation

The air density elevation is the height above sea level at which Windographer calculates the air density. In any dataset that contains wind speed data, Windographer uses air density elevation as part of the calculation of the air density.

The air density elevation is equal to:

The site elevation plus the height of the primary temperature sensor if the dataset contains any temperature sensors,
Or if not, the site elevation plus the height of the primary pressure sensor if the data contains any pressure sensors,
Or if not, the site elevation.

You can specify the site elevation and the primary sensors of each type in the Configure Dataset window.

Example

If the site elevation is 550 m and the dataset contains temperature sensors at 5 m and 40 m above the surface, with the 40m sensor defined as the primary temperature sensor, then the air density elevation will be 590 m, which is the site elevation (550 m) plus the height of the primary temperature sensor (40 m).
