Atmospheric detection method
Cov txheej txheem tseem ceeb ntawm kev tshawb pom huab cua yog: microwave radar suab txoj kev, huab cua los yog foob pob ua ntxaij suab nrov, suab balloon, satellite chaw taws teeb sensing, thiab LIDAR. Microwave radar tsis tuaj yeem ntes cov khoom me me vim tias lub microwaves xa mus rau qhov chaw yog millimeter lossis centimeter tsis, uas muaj qhov ntev wavelengths thiab tsis tuaj yeem cuam tshuam nrog cov khoom me me, tshwj xeeb tshaj yog ntau yam molecules.
Txoj kev siv dav hlau thiab foob pob hluav taws muaj nqi ntau dua thiab tsis tuaj yeem soj ntsuam rau lub sijhawm ntev. Txawm hais tias tus nqi ntawm lub suab nrov balloons qis dua, lawv cuam tshuam ntau dua los ntawm cua ceev. Satellite tej thaj chaw deb sensing tuaj yeem ntes lub ntiaj teb huab cua ntawm qhov loj siv radar on-board, tab sis qhov kev daws teeb meem spatial kuj tsawg. Lidar yog siv los muab cov kev ntsuas atmospheric los ntawm emitting lub laser beam rau hauv cov huab cua thiab siv kev sib cuam tshuam (scattering thiab absorption) ntawm atmospheric molecules los yog aerosols thiab laser.
Vim lub zog directionality, luv wavelength (micron yoj) thiab nqaim mem tes dav ntawm lub laser, thiab lub siab rhiab heev ntawm lub photodetector (photomultiplier raj, ib tug photon detector), lidar muaj peev xwm ua tau siab precision thiab siab spatial thiab temporal daws teeb meem nrhiav pom atmospheric. tsis muaj. Vim nws qhov raug siab, siab spatial thiab lub cev kev daws teeb meem thiab kev soj ntsuam tas li, LIDAR tau txhim kho sai hauv kev tshawb pom ntawm atmospheric aerosols, huab, huab cua paug, atmospheric kub thiab cua ceev.
Hom Lidar tau qhia hauv cov lus hauv qab no:
