KORUS-AQ Mission by a Numbers

  • 3 airplanes with 37 opposite instruments onboard
  • 35 terabytes of scholarship information expected
  • 293 scientists, engineers, moody organisation and other organisation in a field
  • 300+ atmosphere peculiarity belligerent sites opposite South Korea
  • 360 sum moody hours planned
  • 76,000+ lbs of apparatus shipped to South Korea

NASA has marshalled some top-notch systematic expertise to take on a tellurian open health problem: atmosphere pollution. Over a subsequent 6 weeks, scientists will fan out opposite and above South Korea seeking to constraint a perplexing and fugitive lessen and upsurge of changing atmosphere peculiarity conditions. The information they collect will be used to assistance find new solutions to this health threat, not only on a Korean Peninsula though all around a world.

Next week NASA and a Republic of Korea’s National Institute of Environmental Research (NIER) embark on a collaborative Korea United States Air Quality investigate (KORUS-AQ). The KORUS-AQ margin debate will mix observations from aircraft, satellites, ships and belligerent stations with atmosphere peculiarity models to consider and guard atmosphere peculiarity opposite urban, tillage and coastal areas.

Air wickedness is a vital tellurian open health problem. The World Health Organization estimates that 3.7 million beforehand deaths annually can be related to outside atmosphere pollution.  Exposure to soiled atmosphere can means heart disease, stroke, respiratory problems and cancer. Understanding a formidable interplay of factors that change atmosphere quality, including tellurian and healthy emissions, ride by winds in a atmosphere, and windy chemistry are critical for devising strategies to urge internal and tellurian atmosphere quality.

“We wish to pierce over forecasting atmosphere pollution, we wish to change strategies to urge it,” pronounced Jim Crawford, KORUS-AQ principal questioner from NASA’s Langley Research Center in Hampton, Virginia.

The multifaceted apartment of information collected during KORUS-AQ will assistance surprise a growth of a next-generation of space satellites and ground-based systems for atmosphere peculiarity monitoring and forecasting. This information can afterwards be used by preference makers in efforts to urge atmosphere peculiarity on internal and informal scales.

South Korea is an ideal healthy laboratory to lift out air-quality studies. The strong race of a collateral megacity, Seoul, total with a participation of tillage farming communities via a nation concede scientists to investigate both tellurian and naturally constructed emissions. South Korea’s plcae downwind of China also allows scientists to investigate a long-range travel of wickedness into a peninsula.

KORUS-AQ will be formed south of Seoul during Osan Air Base. Two NASA aircraft (the NASA DC-8 and a NASA Beechcraft UC-12B King Air) will join a King Air from Hanseo University in Seosan to lift out concurrent flights over South Korea on 15 days in May and early June.

Flight skeleton will change depending on a daily meteorological conditions and will concede a group to investigate wickedness constructed locally in a Seoul megacity and surrounding areas, wickedness ecstatic from China to a west, and outflow of wickedness over a sea to a east.

The 3 aircraft lift 37 opposite instruments that will magnitude windy gases, particles and solar deviation as good as remote-sensing instruments that will copy satellite measurements. In sequence to finish this large-scale general margin campaign, a group of 293 scientists, engineers, moody organisation and other organisation from a United States, South Korea and 13 other countries are operative together.

In further to aircraft measurements, South Korea has a network of over 300 air-quality belligerent stations in both civic and tillage areas. During a mission, dual categorical belligerent sites as good as over dual dozen other sites will horde a apartment of NASA/U.S. instruments during locations opposite South Korea.

The observations from aircraft and belligerent stations will be compared to and element measurements taken from Earth-observing satellites and will assistance surprise a growth of destiny atmosphere peculiarity satellites. NASA and South Korea are both scheming geostationary atmosphere peculiarity satellite missions to launch in a subsequent few years. The NIER Geostationary Environment Monitoring Spectrometer (GEMS) and NASA’s Tropospheric Emissions: Monitoring of Pollution (TEMPO) instruments will yield rare satellite observations of atmosphere peculiarity over East Asia and North America, respectively. KORUS-AQ information will assistance both countries ready to use a information from these satellites as shortly as they are in orbit.

In further to a airborne, satellite, and belligerent observations collected during KORUS-AQ, a interrelated goal called KORUS-Ocean Color (KORUS-OC) will use dual investigate ships to investigate the waters and atmosphere around South Korea. Starting on May 20, a investigate vessels will take measurements of the ocean’s chemical combination and the daily changes of phytoplankton, a little plants at the bottom of the marine food web that also play a pivotal purpose in Earth’s CO cycle.
