WASHINGTON, DC - I-NASA kanye neRiphabhulikhi yaseKorea benza izinhlelo zocwaningo lwensimu yokusebenzisana ngekhwalithi yomoya ngoMeyi nangoJuni ukuze kuthuthukiswe ikhono lokuqapha ukungcoliswa komoya ngokunembile emkhathini.

Ucwaningo lwe-Korea-US-Air Quality (KORUS-AQ) luzohlola ikhwalithi yomoya kuzo zonke izindawo zasemadolobheni, zasemakhaya nezisogwini zaseNingizimu Korea kusetshenziswa ukubhekwa okuhlangene kwezindiza, iziza ezingaphansi, imikhumbi namasathelayithi. Okutholakele kuzoba neqhaza elibalulekile ekuthuthukisweni kwezinhlelo zokubheka izinzwa ezisekelwe phansi nasemkhathini namamodeli wekhompyutha ukuze kuhlinzekwe ukuhlolwa kwekhwalithi yomoya okuthuthukisiwe kwabathatha izinqumo.

“I-KORUS-AQ iyigxathu eliya phambili emzamweni wamazwe ngamazwe wokuthuthukisa uhlelo lokubheka izinga lomoya emhlabeni wonke,” kusho uJames Crawford, usosayensi ohamba phambili wase-US kulo msebenzi ovela esikhungweni socwaningo seNASA iLangley eHampton, eVirginia. "Womabili amazwe ethu azobe ethula amasathelayithi e-geostationary azojoyina amanye amasathelayithi ohlelweni oluhlanganisa amanethiwekhi angaphezulu, amamodeli ekhwalithi yomoya, namasampula ahlosiwe emoyeni."

Izinga lomoya liyinkinga enkulu yezemvelo e-United States nasemhlabeni jikelele. Ososayensi bazama ukuxegisa abahlanganyeli abahlukene bekhwalithi yomoya, okuhlanganisa ukukhishwa kwendawo okuvela emisebenzini yabantu, ukungcola okuvela kude, nemithombo yemvelo efana nemililo yesizini nothuli olupheshulwa ngumoya.

Inhloko-dolobha yaseNingizimu Korea, iSeoul, ingenye yezindawo zamadolobha amakhulu amahlanu anabantu abaningi emhlabeni. Ngenxa yokuhlukahluka kwendawo yezwe kanye nendawo ekuyo eseduze nezwekazi elikhulu lase-China elikhula ngokushesha kanye nolwandle, imithelela ehlobene nezici eziningi ezilawula ikhwalithi yomoya mikhulu futhi ngokuvamile kulula ukuyikala phezu kwe-peninsula yase-Korea kunakwenye indawo.

"Sisebenzisana nozakwethu baseNingizimu Korea ku-KORUS-AQ, sizothuthukisa ukuqonda kwethu izici ezinemininingwane ezilawula ikhwalithi yomoya, ukuthi izinqubo zixhumana kanjani, nokuthi zishintsha kanjani ngokuhamba kwesikhathi," kusho uCrawford.

Ngokuvumelana nesivumelwano i-NASA esanda kuphothula ne-National Institute of Environmental Research yaseNingizimu Korea, ososayensi baseKorea bazoqoqa okuphawulwe nge-KORUS-AQ phansi nasezulwini ngendiza i-King Air evela eNyuvesi yaseHanseo eSeosan. Ukuze ithathe idatha ngesikhathi sokuhlolwa, i-NASA izonikela ngelabhorethri endizayo ye-DC-8 evela ku-Armstrong Flight Research Center yesikhungo e-Edwards, e-California, kanye ne-Beechcraft UC-12B King Air yase-Langley.

Amathuluzi amahlanu aseNingizimu Korea azoba yingxenye yokukhokhelwa kwe-DC-8 kanti ithuluzi elilodwa le-NASA lizoba endizeni ye-Hanseo. I-DC-8 ye-NASA izoqhuba izindiza zamahora ayisishiyagalombili ukwenza izilinganiso eziqondile zomkhathi ukusuka ekuphakameni kufike kumafithi angama-25,000. I-NASA King Air izondiza phezulu ngezisetshenziswa ezinzwa kude ezilingisa ukubonwa kwesathelayithi. I-Hanseo King Air izokwenza izilinganiso zomkhathi eziqondile zigxile ezindaweni ezingafinyeleleki kalula ku-DC-8 enkulu. Ososayensi nabamodeli bekhwalithi yomoya abavela emazweni womabili bazosebenzisana ukuze bahlele izindiza zezindiza futhi bahlaziye izilinganiso.

I-South Korea igcina inethiwekhi yokuqapha ikhwalithi yomoya esekelwe phansi, eqhubekayo yamasayithi angaphezu kwama-300. Cishe ingxenye yezindawo isendaweni yaseSeoul kanti amaphesenti angaphezudlwana kuka-80 asemadolobheni. I-South Korea izophatha amathuluzi e-NASA kwezinye zezindawo zokuqapha ezithuthukiswayo ze-KORUS-AQ.

I-KORUS-AQ izohlomula ukuthuthukiswa kweqoqo elisha lamasathelayithi esayensi asemkhathini namathuluzi okulindeleke ukuthi yethulwe eminyakeni ka-2018-2022 ezokwenza izilinganiso zekhwalithi yomoya e-Asia, eNyakatho Melika, eYurophu naseNyakatho Afrika. Ithuluzi le-Geostationary Environment Monitoring Spectrometer laseNingizimu Korea lizoqapha ukushintsha kwesimo sezulu kwesikhathi eside futhi lithuthukise izexwayiso zangaphambi kwesikhathi zezehlakalo ezinkulu zokunukubezeka kwe-peninsula yase-Korea kanye nesifunda sase-Asia-Pacific.

I-NASA's Tropospheric Emissions: Monitoring of Pollution mission, ithuluzi elizondiza njengomthwalo okhokhelwayo osingethwe yisathelayithi yezokuxhumana zezentengiselwano ku-geostationary orbit, izoqoqa izilinganiso zokungcoliswa komoya eNyakatho Melika ukusuka e-Mexico City kuya e-Canada. Umsebenzi we-ESA (European Space Agency's) Sentinel-4 uzothatha izilinganiso zekhwalithi yomoya futhi uqaphe i-ozone ye-stratospheric, imisebe yelanga kanye nokuguquguquka kwesimo sezulu eYurophu naseNyakatho Afrika.

I-NASA isebenzisa indawo ephambili yesikhala ukuze yandise ukuqonda kwethu iplanethi yethu eyikhaya, ithuthukise izimpilo, futhi ivikele ikusasa lethu. I-NASA ithuthukisa izindlela ezintsha zokubuka nokufunda izinhlelo zemvelo ezixhumene zomhlaba ezinamarekhodi edatha yesikhathi eside. I-ejensi yabelana ngokukhululekile ngalolu lwazi oluyingqayizivele futhi isebenza nezikhungo emhlabeni wonke ukuze ithole imininingwane emisha yokuthi iplanethi yethu ishintsha kanjani.

LOKHO ONGAKUTHATHE KULESI SIHLOKO:

In accordance with an agreement NASA recently completed with South Korea’s National Institute of Environmental Research, Korean scientists will collect KORUS-AQ observations on the ground and in the air with a King Air aircraft from Hanseo University in Seosan.
KORUS-AQ will benefit the development of a new a constellation of spaceborne science satellites and instruments expected to launch in the years 2018-2022 that will make air quality measurements over Asia, North America, Europe, and North Africa.
Monitoring of Pollution mission, an instrument that will fly as a hosted payload on a commercial communications satellite in geostationary orbit, will collect air pollution measurements over North America from Mexico City to Canada.
