Ai suferit vreodat\u0103 de arsuri solare? Aceast\u0103 arsur\u0103 a pielii este cauzat\u0103 de radia\u021biile ultraviolete (UV) emise de Soare. Arsurile grave nu sunt doar dureroase, ci pot provoca \u0219i cancer de piele.<\/p>\n<\/div>\n

Din fericire, aproape toat\u0103 radia\u021bia UV d\u0103un\u0103toare este absorbit\u0103 de un strat de ozon situat la o altitudine de 20\u201350 km deasupra P\u0103m\u00e2ntului. Cu toate acestea, ozonul este o form\u0103 de oxigen care poate fi distrus\u0103 cu u\u0219urin\u021b\u0103 de anumite substan\u021be chimice create de om.<\/p>\n

\u00cen 1987, principalele \u021b\u0103ri industrializate au convenit s\u0103 elimine treptat aceste substan\u021be chimice. Cu toate acestea, sateli\u021bii au ar\u0103tat c\u0103 sub\u021bierea stratului de ozon a continuat deasupra Antarcticii. Gaura de ozon a atins o dimensiune record \u00een 2000, c\u00e2nd a acoperit aproape 30 de milioane de km\u00b2, aproximativ dimensiunea continentului nord-american. \u00cen 2006, s-a pierdut o cantitate \u0219i mai mare de ozon din atmosfer\u0103, de\u0219i gaura era pu\u021bin mai mic\u0103.<\/p>\n

De asemenea, au ap\u0103rut g\u0103uri de ozon mai mici deasupra Arcticii. Aceste g\u0103uri permit p\u0103trunderea unei cantit\u0103\u021bi mai mari de radia\u021bii UV \u00een zonele dens populate ale Europei.<\/p>\n

Sateli\u021bii ESA, precum MetOp \u0219i Envisat, joac\u0103 un rol esen\u021bial \u00een studiile privind gaura de ozon. Ace\u0219tia le permit oamenilor de \u0219tiin\u021b\u0103 s\u0103 monitorizeze dimensiunea g\u0103urii \u0219i s\u0103 afle mai multe despre factorii care determin\u0103 cre\u0219terea sau mic\u0219orarea acesteia.<\/p>\n

Primul satelit meteorologic european cu orbit\u0103 polar\u0103, MetOp-A, este echipat cu un instrument avansat de monitorizare a ozonului. Envisat dispune de trei instrumente capabile s\u0103 studieze ozonul \u0219i poluan\u021bii care \u00eel afecteaz\u0103 \u00een straturile superioare ale atmosferei.<\/p>","protected":false},"excerpt":{"rendered":"
