Jo l\u00e4hes 30 vuoden ajan jatkuneet kasvihuonekaasumittaukset Sammaltunturilla, Pallas-Yll\u00e4stunturin kansallispuistossa ovat todennetusti korkeatasoisia, osoittaa Ilmatieteen laitoksen Atmospheric Measurement Techniques -tiedelehdess\u00e4<\/a> julkaistu tutkimus. Tutkimuksessa vertailtiin kahden eri laitteiston hiilidioksidi- sek\u00e4 metaanimittauksia, ja laitteistojen v\u00e4liset erot t\u00e4yttiv\u00e4t kirkkaasti kansainv\u00e4liset tarkkuusvaatimukset.<\/p>\n\n\n\n

Hiilidioksidimittaukset alkoivat Pallaksella jo vuonna 1998 ja metaanimittaukset vuonna 2004. Mittauksista n\u00e4hd\u00e4\u00e4n hiilidioksidin kasvaneen tasaisesti noin 2 tilavuuden miljoonasosan (ppm) vuosivauhtia. Metaanipitoisuuksien kasvu on ollut v\u00e4hemm\u00e4n tasaista, kasvaen keskim\u00e4\u00e4rin 8 tilavuuden miljardisosaa (ppb) vuodessa.<\/p>\n\n\n\n

Pallaksen mittaukset edustavat sijaintinsa puolesta globaalia taustailmaa, jota mittaavia asemia on maailmanlaajuisesti vain kourallinen. Pitk\u00e4t ja luotettavat aikasarjat mahdollistavat pitk\u00e4n ajan muutosten ja kausivaihteluiden havaitsemisen sek\u00e4 ekosysteemien ja ilmakeh\u00e4n vuorovaikutusten ymm\u00e4rt\u00e4misen.
