Exchange of reactive trace gases over the biosphere is a key source of reactive organic carbon to the atmosphere and thus influences the formation of both ozone (O3) and secondary organic aerosol (SOA). Both O3 and aerosol particles are short-lived climate forcers and impact the radiative balance of the planet, and their sources and sinks are chemically complex. However, the biosphere also acts as a deposition sink for organic and inorganic compounds, including O3, aerosols, and their precursors. Wet and dry deposition provides a key lever on the lifetime of trace gases and particles in the atmosphere and thus on their potential to influence the radiative balance of the planet. The fluxes of reactive trace gases and particles are part of an atmospheric biogeochemical cycle that includes feedbacks through drought and other climate components.

测量短期气候推动者及其前体的生物圈-大气交换。

在生物圈上反应性微量气体的交换是向大气中反应性有机碳的关键来源,因此会影响臭氧(O 3)和二次有机气溶胶(SOA)的形成。O 3和气溶胶颗粒都是短命的气候推动力,会影响地球的辐射平衡,其源和汇在化学上很复杂。然而,生物圈还充当有机和无机化合物(包括O 3)的沉积池,气雾剂及其前体。湿法沉积和干法沉积为大气中痕量气体和微粒的寿命以及影响行星辐射平衡的潜力提供了关键杠杆。反应性微量气体和颗粒的通量是大气生物地球化学循环的一部分,其中包括通过干旱和其他气候成分的反馈。
