Nzira dzekuona mumhepo
Nzira huru dzekuona mumhepo ndeidzi: microwave radar sounding method, airborne or rocket sounding method, sounding balloon, satellite remote sensing, uye LIDAR. Microwave radar haikwanise kuona tudikidiki nekuti ma microwave anotumirwa kumhepo ari mamilimita kana masendimita masaisai, ane mafungu akareba uye haakwanise kudyidzana netwudiki, kunyanya mamorekuru akasiyana.
Airborne uye rocket kurira nzira dzinodhura uye hazvigone kucherechedzwa kwenguva yakareba. Kunyange zvazvo mutengo wemabharuni ekurira wakadzikira, anonyanya kukanganiswa nekumhanya kwemhepo. Satellite iri kure inonzwa inogona kuona mamiriro epasi rose pamwero mukuru uchishandisa on-board radar, asi kugadzirisa kwenzvimbo kwakadzikira. Lidar inoshandiswa kutora maparamendi emuchadenga nekuburitsa danda relaser mumhepo uye kushandisa kupindirana (kuparadzira uye kunyura) pakati pemuchadenga mamorekuru kana aerosols nelaser.
Nekuda kwekutungamira kwakasimba, pfupi wavelength (micron wave) uye yakamanikana pulse hupamhi hwelaser, uye yakanyanya senitivity yephotodetector (photomultiplier chubhu, single photon detector), lidar inogona kuwana yakanyanya kurongeka uye yakakwirira nzvimbo uye yenguva yekuonesa kugadziriswa kwemhepo. parameters. Nekuda kwehupamhi hwepamusoro, kukwirira kwenzvimbo uye kugadzirisa kwechinguva uye kuenderera mberi kwekutarisa, LIDAR iri kukurumidza kukura mukuona kweaerosols emuchadenga, makore, zvinosvibisa mhepo, tembiricha yemhepo uye kumhanya kwemhepo.
