Br\u00e4nder kan h\u00e4rja b\u00e5de i st\u00e4der och p\u00e5 landsbygden. Skogsbr\u00e4nder kan n\u00e5 temperaturer p\u00e5 upp till 800 \u00b0C och sprida sig med en hastighet p\u00e5 upp till 100 meter per minut, vilket snabbt kan \u00f6del\u00e4gga ett helt omr\u00e5de.<\/p>\n<\/div>\n

\u00c5r 2003 f\u00f6rst\u00f6rdes \u00f6ver en halv miljon hektar skogsmark av br\u00e4nder i s\u00f6dra Europa, vilket orsakade skador f\u00f6r flera miljarder euro. \u00c5r 2010 drabbades omr\u00e5det kring den ryska huvudstaden Moskva av en v\u00e4rmeb\u00f6lja med temperaturer p\u00e5 upp till 40 \u00b0C. Detta ledde till regionens v\u00e4rsta skogsbr\u00e4nder p\u00e5 15 \u00e5r. S\u00e5dana n\u00f6dsituationer kan f\u00f6rv\u00e4rras och bli vanligare om den globala uppv\u00e4rmningen g\u00f6r somrarna torrare och varmare.<\/p>\n

ESA:s jordobservationssatelliter kan anv\u00e4ndas p\u00e5 m\u00e5nga olika s\u00e4tt f\u00f6r att bek\u00e4mpa hotet fr\u00e5n br\u00e4nder \u00f6ver hela v\u00e4rlden.<\/p>\n

De kan avbilda de omr\u00e5den som brinner och identifiera de st\u00f6rsta brandh\u00e4rdarna inom det br\u00e4nda omr\u00e5det. De kan ocks\u00e5 uppt\u00e4cka v\u00e4xthusgaser och r\u00f6kmoln som bildas av br\u00e4nderna.<\/p>\n

Genom att kartl\u00e4gga br\u00e4nder minst tv\u00e5 g\u00e5nger om dagen g\u00e5r det att f\u00f6lja hur de utvecklas. Man kan ocks\u00e5 bed\u00f6ma skadornas omfattning.<\/p>\n

Data fr\u00e5n v\u00e4dersatelliter och jordobservationssatelliter kan kombineras f\u00f6r att ta fram dagliga kartor. Dessa g\u00f6r det m\u00f6jligt f\u00f6r brandm\u00e4nnen att fokusera p\u00e5 de omr\u00e5den som l\u00f6per st\u00f6rst risk.<\/p>\n

Satellitbilder som tagits under m\u00e5nga \u00e5r g\u00f6r det l\u00e4ttare att f\u00f6rutse och f\u00f6rbereda sig f\u00f6r framtida br\u00e4nder.<\/p>","protected":false},"excerpt":{"rendered":"
