What's Happening?
NASA has announced the Hemispheric Airborne Measurements of Air Quality (HAMAQ) project under the EVS-4 program, utilizing aircraft and satellite coordination to enhance air quality models. The initiative aims to improve connections between satellite and surface
networks, evaluate emissions, develop satellite proxies, and investigate factors affecting air quality in urban areas. The program invites participation from instrument and modeling teams, with proposals due by July 21, 2026. A pre-proposal webinar is scheduled for June 24, 2026, to provide further information.
Why It's Important?
This initiative is significant for advancing scientific understanding of air quality and its impact on public health and environmental policy. By integrating satellite and surface data, the project aims to refine air quality models, which are crucial for regulatory and research purposes. Improved models can lead to better-informed policy decisions, potentially reducing pollution and enhancing public health outcomes. The collaboration between NASA and scientific teams underscores the importance of interdisciplinary approaches in tackling complex environmental challenges.
What's Next?
Interested parties must submit Notices of Intent by May 20, 2026, and proposals by July 21, 2026. The pre-proposal webinar will offer insights into the program's objectives and participation requirements. Successful proposals will contribute to the development of comprehensive air quality models, influencing future research and policy directions. Continued collaboration between NASA and scientific teams will be essential for achieving the project's goals.
