ATMO pollen index - Municipal pollen index

The pollen index is a synthetic daily indicator calculated by the approved air quality monitoring associations (AASQA) that describes pollen events at municipal level. It is the aggregated result of the monitoring of pollen concentrations of six taxa: alder, birch, olive, sagebrush, grasses and ambrosia. This index of the day is equal to the most degraded sub-index of the 6 taxa. Relationship between the \_quality code and the qualifier. 1 = Very low 2 = Low 3 = Moderate 4 = Raised 5 = Very high 6 = Extremely high 0 = Unavailable Data source: Atmo France and the approved air quality monitoring associations Additional information: [https://www.atmo-france.org/sites/federation/files/medias/documents/2025-04/Presentation _index_pollen_version_2_April_2025.pdf](https://www.atmo-france.org/sites/federation/files/medias/documents/2025-04/Presentation _index_pollen _version _2_April_2025.pdf)花粉指数是由经核准的空气质量监测协会（AASQA）测算生成的合成性每日指标，用于表征市级层面的花粉污染事件。 该指数整合了桤木、桦树、橄榄、蒿属、禾本科植物以及豚草共6类分类群的花粉浓度监测数据。 当日花粉指数的取值等于上述6类分类群中最劣的子指数。 质量代码与等级标识的对应关系如下： 1 = 极低（Very low） 2 = 低（Low） 3 = 中等（Moderate） 4 = 偏高（Raised） 5 = 极高（Very high） 6 = 极端高（Extremely high） 0 = 无法获取（Unavailable） 数据来源：Atmo France 及经核准的空气质量监测协会 附加信息：[https://www.atmo-france.org/sites/federation/files/medias/documents/2025-04/Presentation _index_pollen_version_2_April_2025.pdf](https://www.atmo-france.org/sites/federation/files/medias/documents/2025-04/Presentation _index_pollen _version _2_April_2025.pdf)
