Custom AirNow Maps - Changing the Forecast Layers
Changing Forecast layers uses a similar methodology to some of the ones explained above.
In this case you use the flayer variable in the URL.
- Today’s Forecast—flayer= forecasttoday
- Tomorrow’s Forecast—flayer= forecasttomorrow
- No Forecast—flayer=none
For example, this is how you would enable tomorrow’s forecast monitors on the standard map: https://gispub.epa.gov/airnow/index.html?flayer=forecasttomorrow&tab=1
Note that an additional variable, tab=1, was included. This is because this variable only applies to the Forecast (tab 1) tab. Tabs are covered in the next section.
