Yadda Sentinel-6 ke Taimakawa

To ta yaya Sentinel-6 Michael Freilich zai taimaka inganta fahimtarmu game da teku da yanayi? Ga abubuwa biyar da ya kamata ku sani:

Sentinel-6 zai ba da bayanai ga masana kimiyya

Tauraron dan adam za su ba da bayanai don taimaka wa masana kimiyya su fahimci yadda sauyin yanayi ke canza gabar tekun duniya da kuma saurin faruwar lamarin. Tekuna da yanayin duniya ba su rabuwa. Tekuna suna ɗaukar fiye da kashi 90 na zafin duniya ta hanyar ƙara iskar gas, wanda ke haifar da fadada ruwan teku. A halin yanzu, wannan fadada ya kai kusan kashi uku na hawan teku, yayin da ruwa daga narke glaciers da kankara zanen gado lissafin ga sauran.

Yawan hawan teku ya karu a cikin shekaru ashirin da suka gabata, kuma masana kimiyya sun yi kiyasin cewa zai kara habaka a cikin shekaru masu zuwa. Yunƙurin ruwan teku zai canza mashigar teku da kuma ƙara tudun ruwa da ambaliya. Don ƙarin fahimtar yadda hawan teku zai shafi mutane, masana kimiyya suna buƙatar bayanan yanayi na dogon lokaci, kuma Sentinel-6 Michael Freilich zai taimaka wajen samar da waɗannan bayanan.

"Sentinel-6 Michael Freilich wani ci gaba ne a auna matakin teku," in ji Josh Willis, masanin kimiyyar ayyuka a dakin gwaje-gwajen Jet Propulsion na NASA a Kudancin California, wanda ke kula da gudummawar NASA ga aikin. "Wannan shi ne karo na farko da muka samu nasarar kera tauraron dan adam da yawa da suka shafe tsawon shekaru goma, tare da sanin cewa sauyin yanayi da hawan teku suna ci gaba da gudana."

Za su ga abubuwan da ayyukan da suka gabata na matakin teku ba za su iya ba

Zai inganta fahimtar canjin yanayi

Ta hanyar faɗaɗa rikodin yanayin yanayin yanayi na duniya, aikin zai taimaka wa masana kimiyya su inganta fahimtar canjin yanayi a duniya. Canjin yanayi yana shafar ba kawai tekuna da saman duniya ba, amma Hakanan yana rinjayar yanayi a kowane matakai, daga troposphere zuwa stratosphere. Kayayyakin kimiyya da ke cikin Sentinel-6 Michael Freilich suna amfani da wata dabara da ake kira fakuwar rediyo don auna yanayin yanayin yanayin duniya.

The Global Navigation Satellite Radio Concealment System (GNSS-RO) kayan aiki ne da ke bin diddigin siginar rediyo daga wasu tauraron dan adam kewayawa da ke kewaya duniya. Daga mahangar Sentinel-6 Michael Freilich, lokacin da tauraron dan adam ya fado kasa da sararin sama (ko ya tashi), siginar rediyonsa yana tafiya cikin yanayi. A cikin yin haka, siginar yana raguwa, mitar ta canza, da kuma karkatar da hanya.
