In some areas, for example, Los Angeles, the AirNow system offers AQI information by small, highly localized reporting areas. Those areas are still there, but on the new system, the dial is populated with the NEAREST report. Even though that report may be from a very localized area, the dial will show the city name. The small reporting areas you may have seen on the old site are still being used and can all be seen on the appropriate state page. For instance, Los Angeles is divided into about 50 smaller AQI reports. The system will show the nearest one, but ALL of them are listed on the California state page.
