Pred 18 meseci so bili znanstveniki obupani, ko je satelit, ki naj bi po\u0161iljal klju\u010dne podatke o podnebnih spremembah, izginil zaradi neuspe\u0161nega izstrelitve. Vendar se je ESA hitro odlo\u010dila za ponovno izgradnjo CryoSata, misija pa je zdaj na dobri poti k ponovni vzpostavitvi. Ko bo CryoSat-2 leta 2009 poletel v vesolje, bo namre\u010d \u0161e zmogljivej\u0161i od svojega predhodnika.<\/p>\n<\/div>\n

Velika prednost satelita CryoSat-2 je njegova zmo\u017enost merjenja sprememb debeline ledene odeje, tako na kopnem kot na morju. Njegov glavni radarski instrument in identi\u010den rezervni instrument bosta lahko preu\u010devala zemeljske ledene plo\u0161\u010de in ledenike v vseh vremenskih razmerah, podnevi ali pono\u010di.<\/p>\n

Da bi se pripravili na izstrelitev, se v Arktiki za\u010denjajo \u0161tevilni terenski poskusi. Eden izmed njih je ekspedicija \u00bbArctic Arc\u00ab, ki poteka v okviru Mednarodnega polarnega leta. Dva belgijska raziskovalca te ekspedicije, Alain Hubert in Dixie Dansercoer, sta se pravkar odpravila na izjemno naporno 110-dnevno potovanje \u010dez zamrznjeno divjino.<\/p>\n

Oba neustra\u0161na raziskovalca bosta, vsak s 130-kilogramskim sani, na katerih bosta preva\u017eala zaloge in opremo, \u2018hodila\u2019 \u010dez vrh sveta, od otoka v Sibiriji do ju\u017ene Grenlandije. Na poti bosta natan\u010dno bele\u017eila globino snega. Tak\u0161ne meritve so izredno koristne za preverjanje metode, s katero se radarske meritve satelita CryoSat pretvarjajo v natan\u010dne podatke o debelini ledu.<\/p>\n

Znanstveniki se bodo sredi aprila odpravili tudi na z ledom prekrite otoke Svalbard. Njihove meritve snega in ledu bodo primerjali s podatki, ki jih bo posredovalo letalo, opremljeno s kopijo radarskega instrumenta CryoSat.<\/p>","protected":false},"excerpt":{"rendered":"
