Introduction 

Display weather hazards: Global ozone forecast 

In this topic, you learn how to add information on global ozone levels to the map. 

We estimate that this will take 1 minute to complete.

Detailed explanation 

Weather hazards 

Display flight hazards using the information provided in the HAZARD tab to optimize flight routes or improve flight decisions based on those hazards. The options include:

• Global ozone forecast: forecasting position and the concentration of the ozone layer

For more details on working with the last three layers in the HAZARD tab, consult the topic, Display weather hazards: EDR turbulence, icing forecast, and EDR thunderstorms forecast.

• EDR turbulence: turbulence at multiple flight levels as well as forecast periods globally or for the North American Mesoscale Model (NAM)
• Icing forecast: forecasts for icing for different flight levels, as well as forecast periods over North America or globally
• EDR thunderstorms forecast: forecast convective activity and intensity for different forecast periods globally or for North America.

The HAZARD tab is available only if you subscribe for weather information for at least one region.   

What does the global ozone forecast look like today?

You can display this information on the map by accessing the appropriate weather layer in the Layers menu.

Click the Layers button.

Click the Global Ozone Forecast slider.

After Global Ozone Forecast is enabled, you can see where different concentrations of ozone occur. In this example, the map shows the forecast for the next six hours. 

The ozone forecast uses two colors to indicate different concentration levels:

Clicking within a depicted shape displays more detailed information.

You can change the time for which the forecast displays to show 12, 18, or 24 hours in the past or in the future.

 For this example, display the forecast time period for 12 hours in the future. 

Click the Forecast hours + button.

In this example, increasing the time offset from 6 to 12 changes the area to which the ozone warning applies.

 When using this layer, be aware that at any given time, ozone may not be present in a high enough concentration to be depicted on the map.

Use the Global Ozone Forecast slider to enable or disable this feature.
