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 siziqhathanisa nezilinganiso ezindala zokulungiswa okuphansi.
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 kaTropomi ngu-7 × 3,5 km2. Lokhu kuvumela ukumbozwa kwansuku zonke komhlaba futhi kuzohlinzeka cishe nge-640GB yemininingwane nedatha ngosuku.
Ngenxa yale mfanelo yolwazi kuzokwazi ukwenza izilinganiso ngendlela engakaze ibonwe ngaphambili. “Manje sesingena enkathini entsha yokukalwa kwezinga lomoya,” kusho uJosef.
"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 uthatha izinqumo zesikhathi esizayo ngokushintsha kwesimo sezulu. Ingasetshenziswa futhi ukulandelela umlotha wentaba-mlilo othinta izindiza nezinsizakalo zokuxwayisa emazingeni aphezulu emisebe.
Imiphumela yokulinganisa yalesi sethelayithi idlule okulindelwe, ngakho-ke kungashiwo ukuthi kuyinto eguqukayo.
