NASA\u2019s DC-8 aircraft takes off from NASA\u2019s Armstrong Flight Research Center Building 703 in Palmdale, California, to conduct test flights as part of the Airborne and Satellite Investigation of Asian Air Quality, or ASIA-AQ mission, that will collect detailed air quality data over several locations in Asia.<\/div>\n

NASA and international researchers are studying the air quality in Asia as part of a global effort to better understand the air we breathe. In collaboration with Korea\u2019s National Institute of Environmental Research (NIER), the Airborne and Satellite Investigation of Asian Air Quality, or ASIA-AQ mission, will collect detailed atmospheric data over several locations in Asia.<\/p>\n

Utilizing aircraft, satellites, and ground-based instruments, the ASIA-AQ team will gather and share data with air quality and government agencies to be used for air quality research and understanding worldwide.<\/p>\n

\u201cOur purpose is to improve the understanding of the factors that control air quality,\u201d said Jim Crawford, principal investigator for the ASIA-AQ mission at NASA\u2019s Langley Research Center in Hampton, Virginia. \u201cMulti-perspective observations are needed because satellites, ground-sites, and aircraft each see different aspects of air quality that need to be connected.\u201d<\/p>\n

While satellite views and ground measurements provide significant data, alone they cannot completely illustrate air quality problems and the sources that cause them. By adding airborne measurements to models along with satellite and ground-based observations, scientists can achieve a multi-dimensional, detailed perspective that evaluates our air quality models from all angles.<\/p>\n

A pair of NASA science aircraft will help provide those additional dimensions to air quality observations. The DC-8 from NASA\u2019s Armstrong Flight Research Center in Edwards, California, is outfitted with 26 instruments and will fly at low-altitudes to collect data from the atmosphere closest to the ground where people and habitats are impacted. Meanwhile, the G-III from NASA\u2019s Langley Research Center in Hampton, Virginia, will fly at 28,000 feet altitude to create a high-resolution map of the pollution distribution in each study area, and how it changes throughout the day. Together with Korean aircraft from NIER, the NASA planes and instruments will supplement and cross-reference the observations made from the ground and satellite instruments.<\/p>\n

\u201cScience missions for air quality [like ASIA-AQ] take a holistic approach of multiple perspectives to better understand our pollution issues,\u201d said Laura Judd, platform scientist for NASA\u2019s G-III aircraft. \u201cIf we can better understand how models simulate our air pollution, then we can forecast when these events unfold, and be able to disseminate that information to the public to make informed decisions.\u201d<\/p>\n

Pollution changes as populations shift, economies ebb and flow, and industries move or evolve. The ASIA-AQ project will improve our ability to measure those changes and how they connect to the global scale. Bringing scientists, aircraft, and instruments together from across Asia and around the world, ASIA-AQ demonstrates how scientific advancement is a collaborative effort.<\/p>\n

\u201cScientists and agencies in each of the participating countries will ensure that ASIA-AQ targets the most important open air quality questions in their specific region,\u201d said Barry Lefer, NASA program scientist for air quality research at NASA Headquarters. \u201cAnd they\u2019ll be the ones to implement improvements in their forecast models and advocate for policy changes.\u201d ASIA-AQ is a joint effort between NASA and Korea\u2019s National Institute of Environmental Research (NIER) and several international organizations including the Department of Environment and Natural Resources Philippines (DENR), the Universiti Kebangsaan Malaysia (UKM), the Geo-Informatics and Space Technology Development Agency Thailand (GISTDA) and the Ministry of Environment Taiwan (MOENV).<\/p>\n
