Aerul este plin de particule minuscule de praf \u0219i pic\u0103turi care plutesc \u00een aer \u2013 cunoscute sub denumirea de \u201caerosoli\u201d. Mul\u021bi aerosoli sunt produ\u0219i de natur\u0103. Printre ace\u0219tia se num\u0103r\u0103 nisipul provenit din furtunile de praf din de\u0219ert, particulele de sare din ocean, cristalele de ghea\u021b\u0103, cenu\u0219a provenit\u0103 din incendii \u0219i erup\u021bii vulcanice.<\/p>\n<\/div>\n

Activit\u0103\u021bile umane contribuie, de asemenea, la cre\u0219terea cantit\u0103\u021bii de aerosoli din atmosfer\u0103. Aerosolii de funingine neagr\u0103 \u0219i de dioxid de sulf sunt emi\u0219i de centralele electrice \u201cpoluante\u201d \u0219i de co\u0219urile de fum ale fabricilor. Al\u021bi aerosoli sunt emi\u0219i de gazele de e\u0219apament ale autovehiculelor \u0219i de motoarele avioanelor.<\/p>\n

Aerosolii sunt at\u00e2t de mici \u00eenc\u00e2t se pot r\u0103sp\u00e2ndi \u00een \u00eentreaga lume. Ace\u0219tia pot provoca astm \u0219i pot duce la apari\u021bia ploilor acide care ucid pe\u0219tii \u0219i copacii. De asemenea, joac\u0103 un rol important \u00een schimb\u0103rile climatice, deoarece absorb \u0219i \u00eempr\u0103\u0219tie lumina soarelui. Datele transmise de sateli\u021bi \u00eei ajut\u0103 pe oamenii de \u0219tiin\u021b\u0103 s\u0103 studieze r\u0103sp\u00e2ndirea aerosolilor \u0219i impactul pe care ace\u0219tia \u00eel au asupra planetei.<\/p>\n

Cele patru instrumente de la bordul satelitului Envisat al ESA sunt utilizate pentru a cartografia concentra\u021biile de particule de praf \u0219i pic\u0103turi de nor, de la nivelul solului p\u00e2n\u0103 la o \u00een\u0103l\u021bime de 100 km. Acestea pot detecta norii de aerosoli \u0219i poluan\u021bi care acoper\u0103 marile ora\u0219e industriale sau p\u0103durile \u00een fl\u0103c\u0103ri. De asemenea, pot identifica urmele de gaze de e\u0219apament l\u0103sate \u00een atmosfera superioar\u0103 de avioanele de linie.<\/p>","protected":false},"excerpt":{"rendered":"
