Tururin ruwa

Yaduwar radiation na sararin samaniya

Acikin yanayin duniya,tururin ruwa yana shanye nau'ikan Infrared(IR)makamashi da yawa,yayin da wasu ba asha suba. Sauran sassan Electromagnetic da tururin ruwa baya shawa kamar buɗewa a cikin yanayi, yana bada damar wutar lantarki ta gudana ciki da waje daga tsarin,kamar taga wanda ke bada damar haske ya shiga da barin. Asalin da John Tyndall ya gano, yawancin infrared da ke fitowa daga sararin samaniya an toshe shi,kuma tururin ruwa(da sauran iskar gas)acikin yanayin duniya yasha shi. Waɗannan kewayon tsawo waɗanda zasu iya kaiwa saman suna zuwa ta hanyar abinda ake kira 'fensho na tururi na ruwa'. Waɗannan tagogin su ne yadda masu binciken sararin samaniya zasu iya kallon sararin samaniya tare da kuma na'urorin daukar hoto na IR, wanda ake kira Infrared astronomy.Rashin hasken rana mai shigowa da kuma hasken rana na duniya mai fitowa a saman sararin samaniya yana kiyaye ma'aunin makamashi na Duniya.Matsakaicin darajar duniya na fitarwa,radiation na dogon lokaci shine 238.5 Wm2,bisa ga binciken Loeb et al.(2009)na lura da tauraron dan adam.Mutum na iya samun tasirin zafin jiki na duniya ta hanyar zaton cewa tsarin sararin samaniya na Duniya yana haskakawa a matsayin baƙar fata daidai da daidaitattun Stefan-Boltzmann na radiation na baƙar fata. Sakamakon zafin jiki shine -18.7 °C. Idan aka kwatanta da +14.5 °C,matsakaicin zafin duniya na farfajiyar Duniya,yana da 33 °C sanyi. Wannan yana nuna cewa farfajiyar duniya ta kai 33 °C da ta fi zafi fiye da yadda za ta kasance ba tare da yanayi ba,Waɗannan tagogin suna bada damar tauraron dan adam masu kewaye don auna makamashi na IR da ke barin duniya, SSTs,da sauran muhimman batutuwa. Dubi shawo kan lantarki ta ruwa:Tasirin yanayi.
