Njira zodziwira mumlengalenga
Njira zazikuluzikulu zodziwira mumlengalenga ndi: njira ya microwave radar sounding, airborne or rocket sounding, sounding balloon, satellite remote sensing, ndi LIDAR. Mafunde a Microwave sangazindikire tinthu ting'onoting'ono chifukwa ma microwave omwe amatumizidwa kumlengalenga ndi mafunde a millimeter kapena centimita, omwe amakhala ndi kutalika kwa mafunde ndipo sangathe kulumikizana ndi tinthu ting'onoting'ono, makamaka mamolekyu osiyanasiyana.
Njira zowomba ndege ndi rocket ndizokwera mtengo kwambiri ndipo sizingawonekere kwa nthawi yayitali. Ngakhale kuti mtengo wa mabaluni olira ndi wotsika, amakhudzidwa kwambiri ndi liwiro la mphepo. Kuzindikira kwakutali kwa satellite kumatha kuzindikira mlengalenga wapadziko lonse lapansi pamlingo waukulu pogwiritsa ntchito radar, koma kusintha kwa malo ndikotsika. Lidar imagwiritsidwa ntchito kupeza magawo am'mlengalenga potulutsa mtengo wa laser mumlengalenga ndikugwiritsa ntchito kulumikizana (kubalalitsa ndi kuyamwa) pakati pa mamolekyu am'mlengalenga kapena ma aerosol ndi laser.
Chifukwa cha mayendedwe amphamvu, kutalika kwafupikitsa (micron wave) ndi kupendekeka kwamphamvu kwa laser, komanso kutengeka kwakukulu kwa photodetector (photomultiplier chubu, single photon detector), lidar imatha kukwaniritsa kulondola kwambiri komanso kuzindikira kwakanthawi kochepa komanso kwakanthawi kwa magawo amlengalenga. Chifukwa cha kulondola kwake, kusintha kwakukulu kwa malo ndi kwakanthawi komanso kuyang'anitsitsa kosalekeza, LIDAR ikukula mofulumira pozindikira ma aerosols a mumlengalenga, mitambo, zowononga mpweya, kutentha kwa mlengalenga ndi liwiro la mphepo.
Mitundu ya Lidar ikuwonetsedwa mu tebulo ili:

Chithunzi chojambula cha mfundo ya radar yoyezera mtambo
mtambo wosanjikiza: mtambo wosanjikiza woyandama mumlengalenga; Kuwala kotulutsa: mtengo wopindika wa utali wosiyanasiyana; Echo: chizindikiro chobalalika kumbuyo chomwe chimapangidwa pambuyo poti kutulutsa kumadutsa mumtambo; Mirror base: malo ofanana a telescope system; Chidziwitso: chipangizo chamagetsi chomwe chimagwiritsidwa ntchito polandila chizindikiro chofooka cha echo.
