Radiation and heat flux maps

For more explanations about solar radiation and latent and sensible flux, please have a look at the specific page concerning the radiation.

The radiation maps are all available at 3h steps.

Solar radiation

Solar radiation over Europe

Solar radiation over Europe

The solar radiation map shows the incoming shortwave radiation in W/m².

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.

Latent heat flux

Latent heat flux over Switzerland

Latent heat flux over Switzerland

The latent heat changes the phase of a substance.

The map shows the latent heat flux in W/m² with the help of a colour scale, combined with streamlines at 10 m above ground.

Sensible heat flux

Sensible heat flux over Switzerland

Sensible heat flux over Switzerland

The sensible heat changes the temperature of a substance.

The map shows the sensible heat flux in W/m² with the help of a colour scale, combined with streamlines at 10 m above ground.
