NASA Earth’s Applied Sciences Program has prepared social media communications for One Health Day 2024, to highlight how NASA satellite and airborne field campaign data can help track air pollution. The team promoted the NASA and U.S. State Department partnership that used NASA satellite data and computer models to develop the ZephAir tool, which now provides three-day forecasts for hazardous PM2.5 air pollution (Facebook: https://www.facebook.com/share/p/14gWK7dxfW/ and Twitter: https://x.com/NASAEarth/status/1853125236415225897). The team also highlighted the Synergistic TEMPO Air Quality Science (STAQS) campaign, where NASA, NOAA, and academic researchers collected and mapped air pollutants at a neighborhood scale in Chicago, New York City, Los Angeles, and Toronto in Summer 2023 (https://x.com/NASAEarth/status/1853125239036604603). These initiatives demonstrate that multidisciplinary collaborations with scientists and community stakeholders are fundamental to monitor air pollution and inform public health decision-making.
