Ukungcoliswa komoya kwesinye isikhathi akulula ukukubona, ikakhulukazi uma singaphakathi komuzi ongcolile. Kukude kuphela futhi ngosizo lwemisebe yelanga lapho kungabonakala izithombe ezikhathazayo zokungcola.
I-European Space Agency (ESA) ikhombisile izithombe zokuqala zesathelayithi ekungcolisweni komoya. Kungokokuqala ukuthi ukungcola kubonakale kusuka esikhaleni ngenxa yesathelayithi i-Sentinel-5P. Ngabe ufuna ukwazi kabanzi ngale mpumelelo?
Ukungcoliswa komoya okuvela emkhathini
Isathelayithi iSentinel-5P yathunyelwa ngo-Okthoba odlule. Ikhwalithi yayo ekulungisweni kwezithombe nedatha imelela ubukhulu obusha. Ukucaciswa nemininingwane etholakala ngayo le datha kufana uma singabona ukungcoliswa komoya ku-HD ephelele, uma kuqhathaniswa nezindala, izilinganiso zokucaca eziphansi. Lokhu kuthuthukiswa ku- Izithombe ze-HD zokungcola komoya Kuyisinyathelo esihle sesayensi.
UJosef Aschbacher ungumqondisi we-ESA's Earth Observation Programs, ebiphethe ukwethula le satellite ekwazi ukubamba nokubonisa ukungcoliswa komoya ngekhwalithi ye-HD.
Isathelayithi ifake iTropomi, i-spectrometer yama-multispectral ehamba phambili kunazo zonke kuze kube manje. Ngenxa yalokhu, ikhwalithi yezithombe ezitholakele iphakeme kakhulu. Kusukela manje, le satellite izophatha ukukala amagesi atholakala emkhathini, afaka i-nitrogen dioxide, i-ozone, i-carbon monoxide, i-methane, i-formaldehyde, i-sulfur dioxide nama-aerosols. .
Usayizi wamaphikseli we-Tropomi ngu-7×3,5 km2. Lokhu kuvumela ukufakwa kwansuku zonke komhlaba wonke futhi kuzohlinzeka cishe ngama-640 GB wolwazi nedatha ngosuku. Lo mthamo wedatha uzoshintsha ukuqonda kwethu ikhwalithi yomoya emhlabeni wonke, okuzobaluleka kakhulu ekuqondeni amazwe angcolisa kakhulu kanye nemiphumela yokuguquguquka kwesimo sezulu.
Ngenxa yale khwalithi yolwazi, izilinganiso zingenziwa ngendlela engakaze ibonwe ngaphambili. "Manje singena enkathini entsha yokulinganisa izinga lomoya," kusho uJosef. Ngaphezu kwalokho, le sathelayithi izobaluleka ezifundweni imiphumela yokufudumala kwembulunga yonke, ezixhumene kakhulu nekhwalithi yomoya.
"Sine cishe ama-wavelengths angama-4.000 nge-spectrum ngayinye futhi sikala cishe ama-spectra angama-450 ngomzuzwana nezigidi ezingamashumi amabili zalokhu kubhekwa ngosuku“Kusho uPepijn Veefkind, ovela eRoyal Netherlands Meteorological Institute, lapho ekhombisa izithombe eziningi ezenziwe ngemininingwane ethunyelwe yiSentinel-5P.
Inhloso yalolu hlelo olusha ukubuka uMhlaba ukuhlinzeka ngolwazi ngekhwalithi yomoya ngesikhathi sangempela. Lokhu kuzosiza kakhulu lapho kuthathwa izinqumo mayelana nokushintsha kwesimo sezulu. Ingasetshenziswa futhi ukulandelela umlotha wentaba-mlilo othinta izindiza nezinsizakalo zokuxwayisa emazingeni aphezulu emisebe.
Imiphumela yokulinganisa yalesi sathelayithi idlule obekulindelekile, ngakho-ke kungashiwo ukuthi iyinto eguquguqukayo. Le mpumelelo iphawula inkathi entsha ekuqondeni kwe ukungcola kanye nomthelela wako futhi izosivumela ukuthi sibhekane nezinkinga zemvelo ngokunembe kakhudlwana.
