Solar radiation

Short wave radiation

These maps show the expected incoming solar short wave radiation with colours as specified in the map legend. It represents the incoming solar radiation, and that is why it is mainly equal to zero during the night (no sun). This map gives also an indication on the cloud coverage. Radiation is expressed in Watt per square metre (W/m²).

Soaring index

Soaring index

These maps show the dimensionless soaring index with colours as indicated in the map's legend. A low soaring index indicated no or weak thermals whereas a high soaring index indicates possible thunderstorms.

In-flight icing

In-flight icing

These maps show the dimensionless expected risk of in-flight icing. It is visualised with colours as specified in the colour bar and is available in different altitudes.

Boundary layer height

Boundary layer height

These maps show the height of the boundary layer in metres (m) with colours as defined in the colour bar. The boundary layer is the lowest part of the troposphere and is defined as the layer in which friction with the Earth's surface influences the air flow. Typically, it is a few hundreds meters to 2 km deep.
