Ana iya amfani da radiation na Infrared don auna duka zafin jiki na farfajiyar (ta amfani da "window" wavelengths wanda yanayi yake bayyane), da kuma zafin jiki ya kasance (ta amfani le wavelength wanda yanayin ba a bayyane yake ba, ko auna saman yanayin girgije a cikin windows na infrared).

Satellites da aka yi amfani da su don dawo da yanayin zafi ta hanyar auna yanayin infrared na zafi gabaɗaya suna buƙatar yanayin girgije. Wasu daga cikin kayan aikin sun hada da Advanced Very High Resolution Radiometer (AVHRR), Along Track Scanning Radiometers (AASTR), Visible Infrared Imaging Radiometer Suite (VIIRS), Atmospheric Infrared Sounder (AIRS), da ACE Fourier Transform Spectrometer (ACE‐FTS) a kan tauraron dan adam na Kanada SCISAT-1.

Ana samun tauraron dan adam na yanayi don ƙaddamar da bayanin zafin jiki na teku (SST) tun 1967, tare da abubuwan farko na duniya da suka faru a cikin shekara ta 1970.  Tun daga shekara ta 1982,  ana amfani da tauraron dan adam don auna SST kuma sun ba da damar bambancin sararin samaniya da na lokaci don a kalli shi sosai. Misali, an yi amfani da canje-canje a cikin SST da aka saka idanu ta hanyar tauraron dan adam don yin rikodin ci gaban El Niño-Southern Oscillation tun daga shekarun 1970.

A cikin ƙasa maido da zafin jiki daga annuri yana da wahala, saboda rashin daidaituwa a saman.  An gudanar da bincike kan tasirin tsibirin zafi na birane ta hanyar hotunan tauraron dan adam.  Ta amfani da fasaha na fractal, Weng, Q. da al. Halin yanayin sararin samaniya na tsibirin zafi na birane.  Ana iya amfani da hotunan tauraron dan adam infrared na ci gaba mai tsayi, idan babu girgije, don gano ƙarancin ƙarancin ( yanayin yanayi ) kamar yanayin sanyi a matakin ƙasa.  Yin amfani da dabarar Dvorak, za a iya amfani da hotunan tauraron dan adam infrared don tantance bambancin zafin jiki tsakanin ido da yanayin zafin saman girgije na tsakiyar tsakiyar babban cyclones na wurare masu zafi don ƙididdige matsakaicin iskar da ke dawwama da mafi ƙarancin matsi na tsakiya .
