Implementation of sulfur hexafluoride (SF6) in the Belgian Assimilation System for Chemical ObsErvations ...

<!--!introduction!--> Sulfur hexafluoride (SF 6 ) is a greenhouse gas that is emitted at the surface because of its use as an insulator in electric power systems. Due to its quasi-linear emission growth and its very long lifetime, SF 6 can be used as a tracer for the Age of Air (AoA) to diagnose changes in the Brewer Dobson Circulation (BDC). The chemistry of SF 6 has been implemented in the Chemistry Transport Model (CTM) of the Belgian Assimilation System for Chemical ObsErvations (BASCOE). Reaction rates were taken from previous studies while an electron density has been taken from EM... Mehr ...
