摘要: Biogenic volatile organic compounds (BVOCs) play a central role in atmospheric chemistry via their high reactivity the gas phase and participation new particle formation secondary aerosol formation. The emissions of BVOC to atmosphere depend on several climate-related variables, making these part complex, yet potentially very important, climate feedback mechanisms. Here we illustrated BVOCs enhancing gross primary production (GPP) cloud droplet number concentrations. first phenomena forms positive loop for terrestrial carbon sink (GPP feedback), whereas second one negative ambient temperature increase (temperature feedback).
