Local Environmental Conditions
Aranjuez's Royal Palace gardens and the Tagus and Jarama river floodplain are the defining local pollen landscape, with extensive poplar groves and plane trees as particularly significant sources alongside oak. The Royal Palace gardens and riverside poplar plantations are among the most significant local pollen sources, while surrounding Castilian farmland extends grass and crop pollen across the historic royal town.
Aranjuez's Royal Palace poplar groves and the Tagus and Jarama river floodplain produce a season opening from January with poplar and plane before oak peaks through April. Grass from surrounding Castilian farmland peaks through May and June before mugwort and nettle extend exposure into September. The riverside woodland is a particularly significant local source and the dry continental climate means fewer rainfall interruptions.

How often is the Aranjuez pollen forecast updated?

Does pollen in Aranjuez come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Aranjuez 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 Aranjuez, 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. |
