Aerosure

1. Gathering Data from All Directions:
The app retrieves real-time data from air quality monitoring stations nationwide and displays it as numerical values ​​on a map, showing you the PM2.5 level closest to your location first.

2. Filling in Blank Spaces (Key Feature: Interpolation):
Normally, if you're in an area without a monitoring station, typical apps won't show the reading, or they'll show readings from stations far away. Aerosure uses an intelligent calculation system, analyzing data from surrounding stations to estimate the actual PM2.5 level at your location (like coloring a gradient to show the overall picture of the province).

3. Identifying Dust Sources (Feature: Hotspot):
The app connects to satellites to show where "hotspots" or forest/agricultural burning are located. You'll see them as fire symbols on the map, immediately indicating whether the high PM2.5 levels today are due to nearby sources or originating from a specific direction.
