Advances in aErosol Retrievals and Impacts on South america

forthcoming

AERIS aims to build an international, cross-sectoral network to advance atmospheric sciences by improving vertically-resolved atmospheric characterization techniques, including near-surface regions. The project unites European academic and commercial institutions with North and South American partners (LALINET). AERIS enhances measurement techniques, connects international observation programs, and creates opportunities for early warning systems, business innovation, and job creation. The main objective is to advance retrieval capabilities for biogenic and non-biogenic aerosols over South America, enabling data with applications in health, hydrology, air quality, and climate. This will support a regional early warning system with global implications, benefiting aviation, biodiversity, and space mission validation. Specific goals include: (1) Implementing quality assurance and calibration for vertically resolved and near-surface measurements; (2) Optimizing inversion algorithms for aerosol property retrievals; (3) Enhancing synergies between instruments to improve spatial and temporal data; (4) Developing predictive models linking aerosols to health impacts; and (5) Investigating aerosol-induced cloud nucleation and its effects on the hydrological cycle. South America faces critical atmospheric challenges with global consequences. Limited infrastructure and monitoring networks hinder accurate data collection and climate modeling, weakening public policies and international cooperation. AERIS addresses these challenges by integrating high-quality, vertically resolved atmospheric data with near-surface imagery, advancing aerosol characterization in South America. This unique database will strengthen regional and global atmospheric science. To achieve these goals, AERIS includes an ambitious consortium and proposes secondments, workshops, and training activities to foster a shared culture of research and innovation.
