Cloud maps
Clouds (density)
These maps show the density of the cloud cover. Grey means denser, while white means less dense. Combinations with line plots are also possible. You can add streamlines or temperatures for a specific altitude for example. More: see clouds .
Convective clouds vertical extent
These maps show the vertical extent of the convective clouds with colours as indicated in the legend. The extent is expressed in kilometres (km). More: see clouds .
Convective cloud base/top
These maps show the height of the base and top respectively of convective clouds. Both are expressed in metres (m) and visualised with colours as indicated in the legend. More: see clouds .
Cloud base/top
These maps show the height of the base and top of clouds. Both are expressed in metres above sea level (m asl) and visualised with colours as indicated in the legend. In addition, white, blue, black or no shading give information about the cloud top height above ground.
- Black hatches: Cloud top lower than 1'000 m asl ;
- Blue lines: Cloud top between 1'000 m and 3'000 m asl ;
- No lines and no hatches: Cloud top between 3'000 m and 6'000 m asl ;
- White lines: Cloud top height higher than 6'000 m (ice clouds, cirrus clouds) .

Satellite
The satellite images show the cloud distribution. You can add line plots to the satellite images to get more information, such as temperature or streamlines for instance. More: see clouds .
Visibility
These maps show the horizontal visibility as a distance in metres (m) with colours as specified in the colour bar. More: see visibility .
