M\u00f6\u00f6duvale tulnukale paistaks Maa veemaailmana, mida katavad suures osas ookeanid ja pilved. Ilma selle v\u00e4\u00e4rtusliku vedelikuta ei eksisteeriks elu Maal. Siiski on meil planeedi vee ja selle m\u00f5ju kohta ilmale ja kliimale veel palju teadmata. ESA j\u00e4rgmine Earth Explorer-missioon, tuntud kui SMOS, peaks andma m\u00f5ned vastused.<\/p>\n<\/div>\n

Vesi on ainus looduslik aine, mis v\u00f5ib Maal esineda nii gaasi, vedeliku kui ka tahke ainena. Kui p\u00e4ike seda soojendab, aurustub vesi ja muutub gaasiks (veeauruks). See gaas t\u00f5useb \u00fcles ja jahtub, moodustades pilved ja vihma. Vihm langeb tagasi maapinnale, millega veeringlus l\u00f5peb.<\/p>\n

Kuigi enamik veeaurust p\u00e4rineb ookeanidest, vabaneb umbes k\u00fcmnendik taimedest ja pinnase aurustumise teel. Kui pinnas muutub aga liiga m\u00e4rjaks, v\u00f5ib see p\u00f5hjustada \u00fcleujutusi ja pinnase erosiooni. Liiga v\u00e4he niiskust ja maa muutub k\u00f5rbe. Praegu tehakse mulla niiskuse m\u00f5\u00f5tmisi v\u00e4he, kuid see on muutumas t\u00e4nu SMOSi k\u00e4ivitamisele.<\/p>\n

Satelliit m\u00f5\u00f5dab ka ookeanide soolsust (\u2018soolakust\u2019), otsides piirkondi, mis on m\u00e4rksa soolasemad ja seet\u00f5ttu tihedamad. Sellised erinevused m\u00f5jutavad ookeanivoolusid, mis omakorda m\u00f5jutavad ilma ja kliimat.<\/p>\n

SMOS-il on spetsiaalne seade, millega m\u00f5\u00f5detakse nii mulla niiskust kui ka ookeani soolsust. Y-kujulistel harudel asuvad 69 vastuv\u00f5tjat m\u00f5\u00f5davad pinnalt tulevat mikrolainekiirgust. Need suudavad tuvastada mulla niiskust, mis on vaid 4% \u2013 see vastab \u00fchele teelusikat\u00e4iele veele k\u00e4esolevas kuivas mullas. Kolmeaastase missiooni jooksul koostatakse esimesed kosmosest tehtud \u00fclemaailmsed mullaniiskuse ja ookeani soolsuse kaardid.<\/p>","protected":false},"excerpt":{"rendered":"
