A major step forward in air quality visualisation and understanding - we’ve released real-time source apportionment in MyAir. You’ll now be able to identify which key sources of NOx and PM₂.₅ are causing air pollution. We’re especially proud of our PM₂.₅ domestic wood burning emissions 🔥
New Features
Source Apportionment Pie Charts
We’ve introduced pie charts for Source Apportionment, making it easier to visually analyse PM and NOx pollution sources at a glance. This enhancement helps users quickly identify the major sources contributing to pollution.
How do I get this? If you’re in the UK, we’ve got you covered! All your existing and new Zephyrs / Virtual Zephyrs will show this information in ‘analysis’.
Outside of the UK? Please get in touch, we’d love to create this for you.

EarthSense Help Centre Integration
Users now have direct access to HelpKit, a comprehensive knowledge base for EarthSense products and services, right within MyAir. Easily find answers and guidance on EarthSense tools, improving user support and knowledge discovery.

New Map Layers
Expanded mapping options with two new layers:
- OpenStreetMap (OSM) Layer: A familiar map base that offers detailed location context.
- Satellite Layer: View real-world satellite imagery to enhance environmental analysis and tracking.
- Default Greyscale Map Layer: A new greyscale map layer has been set as the default for MyAir maps. This cleaner, minimalistic base layer enhances visual clarity, making your air quality data stand out more effectively.

Enhancements
Location Colour Map Overlays
Introducing color-coded overlays for each location, allowing users to distinguish different areas visually and making map navigation more intuitive, especially in dense or complex regions.

Enhanced Device Symbols
Device symbols on maps have been upgraded to improve clarity and recognition. This update makes devices more visible and distinct, especially in crowded maps, facilitating easier monitoring and management.
Improved Analysis Averages
Analysis averages now display with color-coded species tiles that align with the time-series charts. This visually cohesive design streamlines data interpretation, making it easier to spot trends and patterns across different data points.
Improved Datetime UI
The datetime picker has been redesigned for simplicity, with added presets for quickly selecting specific date ranges. This improvement streamlines navigation, saving time when setting or adjusting date filters.
