2021年，世界卫生组织（WHO）空气质量指南针对六种主要空气污染物进行了修订。由于自然来源和背景水平的原因，许多国家可能无法达到PM2.5和O3的新指导水平。由于大气化学作用，NO2的减少可能会增加O3。必须有针对具体区域的科学专门知识，以指导地方空气质量管理，使之实现更适当的世卫组织临时目标，并控制可改变的因素，特别是考虑到大气化学因素。IGAC项目旨在通过区域工作组、专题活动和定期会议，包括两年一度的IGAC科学会议，建立这种科学领导地位，促进空气质量和大气化学研究方面的合作。
In 2021, the World Health Organization (WHO) air quality guidelines were revised for six key air pollutants. The new guideline levels for PM2.5 and O3 may be unattainable for many countries due to natural sources and background levels. Reductions in NO2 may increase O3 due to atmospheric chemistry. Regional-specific scientific expertise is necessary to guide local air quality management towards more appropriate WHO interim targets and controls on modifiable factors especially considering atmospheric chemistry. The IGAC project aims to build such scientific leadership and foster collaboration in air quality and atmospheric chemistry research through regional working groups, topical activities, and regular meetings including the biennial IGAC science conference.
