Saxanka birta ee dhuumaha waxaa loo isticmaalaa in lagu sameeyo dhexroorka weyn ee tuubooyinka alxanka ah kaas oo qaada saliidda iyo gaaska dabiiciga ah, oo sidoo kale loo yaqaan saxan birta tuubada. Hadda dad badan oo adduunku waxay diiradda saaraan ilaalinta deegaankeena, gaaska cusub ee tamarta nadiifka ah ayaa si weyn loo isticmaalaa iyada oo loo marayo dhuumaha. Taargooyinka birta ee dhuumaha ayaa leh awood ay iskaga caabiyaan cadaadiska sare, daxalka atmospheric iyo heerkulka hoose ee ku xeeran. API X120 oo naloo soo bandhigay waxay lahayd sifooyin farsamo oo ka sarreeya heerka caalamiga ah.
