\u00d5hk on t\u00e4is pisikesi \u00f5hus h\u00f5ljuvaid tolmuosakesi ja pisaraid \u2013 neid nimetatakse \u201caerosoolideks\u201d. Paljud aerosoolid tekivad looduses. Nende hulka kuuluvad k\u00f5rbetormidest p\u00e4rit liiv, ookeanist p\u00e4rit soolaosakesed, j\u00e4\u00e4kristallid ning tulekahjude ja vulkaanipurskete tuhk.<\/p>\n<\/div>\n

Inimtegevus suurendab samuti aerosoolide kogust atmosf\u00e4\u00e4ris. Must tahm ja v\u00e4\u00e4veldioksiidi aerosoolid t\u00f5usevad \u00f5hku \u201csaastavatest\u201d elektrijaamadest ja tehase korstnatest. Muid aerosoolide heitmeid tekitavad autode heitgaasid ja lennukite mootorid.<\/p>\n

Aerosoolid on nii v\u00e4ikesed, et v\u00f5ivad levida \u00fcle kogu maailma. Need v\u00f5ivad p\u00f5hjustada astmat ning tekitada happevihma, mis tapab kalu ja puid. Samuti m\u00f5jutavad need kliimamuutust, kuna neelavad ja hajutavad p\u00e4ikesevalgust. Satelliitidelt saadud andmed aitavad teadlastel uurida aerosoolide levikut ja nende m\u00f5ju planeedile.<\/p>\n

ESA satelliidi Envisat pardal asuvaid nelja m\u00f5\u00f5teriista kasutatakse tolmuosakeste ja pilvetilgade kontsentratsioonide kaardistamiseks maapinnast kuni 100 km k\u00f5rguseni. Need suudavad tuvastada aerosoolide ja saasteainete pilved, mis katavad suuri t\u00f6\u00f6stuslinnu v\u00f5i p\u00f5levaid metsi. Samuti suudavad need eristada lennukite poolt \u00fclemisse atmosf\u00e4\u00e4ri j\u00e4etud heitgaasij\u00e4lgi.<\/p>","protected":false},"excerpt":{"rendered":"
