ROSES-25 A.12 HAMAQ Science Team clarified; proposals due July 21, 2026

Hemispheric Airborne Measurements of Air Quality (HAMAQ) is a NASA-funded project under the EVS-4 program that uses two aircraft (NASA’s B777 & P-3B) to sample in coordination with satellites (like TEMPO) and surface observations to develop a multi-perspective view of air quality conditions useful for challenging and improving models.

Program element A.12 HAMAQ Science Team (ST) will work together to address four related objectives. Objective 1. Improve connections between satellites and surface networks through chemically detailed, vertically- and diurnally-resolved measurements. Objective 2.

Evaluate the magnitude and timing of emissions and their source apportionment to inform inventories and their relationship to satellite column observations. Objective 3. Investigate and further develop satellite proxies for air quality. Objective 4. Investigate the diversity of factors controlling air quality across multiple urban areas.
