A horizon scene can be added to account for any far shading effects on the system. Clicking the Add (+) button will display an empty field for azimuth and elevation angle of the horizon point.

Repeat this process until the desired number of horizon points are added.

You can also automatically import a Horizon Scene from Meteonorm.  Click the Import Meteonorm Scene button and PlantPredict will use the Latitude and Longitude of your Project to import a Horizon Scene for your prediction.  All 360 degrees of Horizon Scene are available via the Meteonorm API; however, PlantPredict will analyze each point and only import those points where the Elevation Angle changes from the previous point.  This simplifies the scene and reduces the number of points that are required to create your Horizon Scene
