NASA Armstrong Flight Research Center’s DC-8 aircraft will fly over Central Valley and surroundings areas as part of an air quality field study. Residents in the areas below will see and hear the aircraft as it flies to achieve these measurements.

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’s 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.

In honor of Women’s History Month, we caught up with the ASIA-AQ team on the other side of the Earth and asked the women from Langley about their inspirations and challenges as scientists. The ASIA-AQ (Airborne and Satellite Investigation of Asian Air Quality) mission is an international cooperative field study designed to address local air quality challenges. ASIA-AQ will contribute to improving the integration of satellite observations with existing air quality ground monitoring and modeling efforts across Asia.

NASA - The DC-8 aircraft returned to NASA’s Armstrong Flight Research Center Building 703 in Palmdale, California, on April 1, 2024, after completing its final mission supporting Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ). The aircraft and crew were welcomed back with a celebratory water salute by the U.S. Air Force Plant 42 Fire Department.

NASA Earth Observatory - In spring 2024, an international field campaign—ASIA-AQ (Airborne and Satellite Investigation of Asian Air Quality)—headed to Thailand to take a close look at the haze. During the last two weeks of March 2024, NASA’s DC-8 and Gulfstream III aircraft flew several flights over Chiang Mai, Bangkok, and rural areas surrounding the cities to sample air quality with several sensors. At the same time, satellites observed the haze from above.

Each year in January and February, satellites begin to detect waves of smoke and fire in Southeast Asia, particularly in highland forests in Cambodia, Laos, Myanmar, and Thailand. Fire activity continues to increase through March and April, reaches a peak during the height of the dry season, and then fades in May with the start of the rainy season.

Chiang Mai, the largest city in northern Thailand, is famed for having hundreds of Buddhist temples, some of which date to the city’s founding in the 13th century. This rich history—and easy access to hiking, waterfalls, and hot springs in the surrounding highlands, as well as being the setting of a hit movie in 2012—has turned the city into a hub of tourism that hosts as many as 10 million visitors per year.
