Tulipalot voivat levit\u00e4 yht\u00e4 lailla kaupungeissa kuin maaseudullakin. Mets\u00e4palot voivat saavuttaa jopa 800 \u00b0C:n l\u00e4mp\u00f6tilan ja levit\u00e4 jopa 100 metri\u00e4 minuutissa, tuhoamalla nopeasti kokonaisen alueen.<\/p>\n<\/div>\n

Vuonna 2003 tulipalot tuhosivat yli puoli miljoonaa hehtaaria mets\u00e4maata Etel\u00e4-Euroopassa, mik\u00e4 aiheutti useiden miljardien eurojen arvosta vahinkoja. Vuonna 2010 Ven\u00e4j\u00e4n p\u00e4\u00e4kaupungin Moskovan ymp\u00e4rist\u00f6ss\u00e4 koettiin helleaalto, jonka aikana l\u00e4mp\u00f6tila nousi jopa 40 \u00baC:een. T\u00e4m\u00e4 johti alueen pahimpiin mets\u00e4paloihin 15 vuoteen. T\u00e4llaiset h\u00e4t\u00e4tilanteet voivat pahentua ja yleisty\u00e4, jos ilmaston l\u00e4mpeneminen tekee kesist\u00e4 kuivempia ja kuumempia.<\/p>\n

ESAn maanseurant satelliitteja voidaan hy\u00f6dynt\u00e4\u00e4 monin tavoin tulipalojen aiheuttaman uhan torjumiseksi ymp\u00e4ri maailmaa.<\/p>\n

Niiden avulla voidaan kuvata palavia alueita ja tunnistaa palaneen alueen merkitt\u00e4vimm\u00e4t kuumat kohdat. Niiden avulla voidaan my\u00f6s havaita tulipalojen tuottamia kasvihuonekaasuja ja savupilvi\u00e4.<\/p>\n

Kartoittamalla tulipaloja v\u00e4hint\u00e4\u00e4n kahdesti p\u00e4iv\u00e4ss\u00e4 voidaan selvitt\u00e4\u00e4, miten ne etenev\u00e4t. My\u00f6s vahinkojen laajuus voidaan arvioida.<\/p>\n

S\u00e4\u00e4satelliiteista ja maapallon havainnointisatelliiteista saatavia tietoja voidaan yhdistell\u00e4 p\u00e4ivitt\u00e4isten karttojen laatimiseksi. N\u00e4iden avulla palomiehet voivat keskitty\u00e4 suurimmassa vaarassa oleviin alueisiin.<\/p>\n
