Westside Path - Pollen and Air Quality Forecast for Today
Pollen Today
Pollen levels are low to moderate today, with ragweed and grass as the main active species. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, pollen exposure peaks at 0.0 km after start.
Air Quality Today
Air quality along the route is moderate. PM10 (45.8/100) is moderate, while PM2.5 (27.2/100) is fair. The remaining pollutants stay at good levels. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, air quality is at its worst 0.0 km after start.

Environmental Exposure Detail
Westside Path: A 0.88 km urban walking route about 9.5 km from Atlanta city centre. It follows a mostly paved, urban course through the city streets.
At Westside Path, pollen typically peaks in spring and early summer: birch around April-May, then grass through June-July, tapering off by autumn. The warmest stretch here, around 27°C in July, tends to coincide with the most active pollen release, while the cooler spell around 5°C in January lines up with the quietest period. As a mainly urban route, air pollution here is often worse on cold mornings, when traffic fumes get trapped near the ground, and on warm, still days, when ozone can build up — both affecting air quality more than pollen.

Frequently Asked Questions
Where is air quality worst on the Westside Path route?
Based on today's forecast, PM10 is forecast at moderate levels along the route today (45.8/100). Air quality is at its worst after 0.0 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Westside Path course?
Pollen exposure peaks at km 0.0 today. This changes through the season as different pollen species become active.
When is pollen worst during the Westside Path season?
Pollen seasons vary by location. Tree pollen (birch, alder) typically peaks in spring, while grass pollen rises in May-June.
How often is this forecast updated?
Updated four times daily. See the timestamp below for the most recent update.
Are pollen levels in Westside Path based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Westside Path, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
