Background<\/h2>\n
In 2028, HAMAQ will conduct two deployments: one over Mexico City in the spring and another over Atlanta in summer. These contrasting environments serve as ideal testing grounds for strengthening satellite\u2011to\u2011ground connections and improving air\u2011quality models.<\/p>\n
The mission will use two coordinated NASA aircraft. NASA’s B777 will map pollution from above with remote\u2011sensing instruments, while the P\u20113 will fly closer to the surface to measure aerosols, gases, and boundary\u2011layer structure. Combined with satellite data from TEMPO<\/a> \u00a0(Tropospheric Emissions: Monitoring of Pollution) and ground observations, these measurements are designed to support more accurate air quality insights.<\/p>\n The campaign’s multi-platform observing strategy is designed to address several key questions:<\/p>\n The campaign’s integrated observing system combines satellite, airborne, and ground assets to provide a comprehensive view of air quality. Remote sensing from NASA\u2019s B777 aircraft will map trace gases like nitrogen dioxide and formaldehyde at a high resolution, supporting geostationary satellite observations and validating TEMPO products. Instruments attached to NASA\u2019s P\u20113 aircraft will measure fine particles, chemical components, and aerosols by flying low\u2011level patterns above Mexico City and Atlanta.<\/p>\n The campaign will also contribute to the Atmospheric Composition Virtual Constellation, an international coordination effort led through the Committee on Earth Observation Satellites. This effort brings together atmospheric-composition observations from multiple space agencies and satellite missions to function as a unified system advancing global consistency in air quality measurements. HAMAQ\u2019s atmospheric measurements will refine air\u2011quality models and scenario testing. Together, these efforts will provide new insights into emissions, atmospheric chemistry, and pollution transport to better support air\u2011quality management.<\/p>\n The EVS-4 missions: FARMFLUX<\/a> | FORTE<\/a> | HAMAQ<\/a> | INSPYRE<\/a> | LACCE<\/a> | SNOW4FLOW<\/a><\/p>\nResearch Questions<\/strong><\/h2>\n
