Light Pollution Map

What is Light Pollution Map

Light Pollution Map is an advanced web-based platform that visualizes global artificial night sky brightness using satellite data from NOAA's VIIRS/DNB sensors. The website transforms complex scientific data into easily interpretable color-coded maps, showing light pollution levels from pristine dark skies to heavily polluted areas. It provides historical data from 2012 onwards, allowing users to track changes in night sky brightness over time. The platform uses the Bortle Scale and radiance measurements (cd/m²) to quantify light pollution levels, making it a valuable resource for both scientific research and public awareness.

Common Questions

1. How often is the data updated?

Data updates occur monthly with new satellite imagery.

2. How accurate is the map?

Accuracy varies by location, with pixel resolution around 750m×750m.

3. Can I contribute my own measurements?

Yes, users can submit ground-based measurements.

4. What does the color coding mean?

Colors range from blue (dark skies) to red/white (heavy pollution).

5. Is historical data available?

Yes, data from 2012 onwards is accessible.

6. How can I use this for astronomy?

The map helps identify dark sky locations and predict viewing conditions.
