摘要: A major portion of tropospheric photochemistry occurs in the tropics. Deforestation, colonization, and development tropical rain forest areas could provoke significant changes emissions radiatively photochemically active trace gases. brief review studies on trace-gas pristine disturbed habitats is followed by an effort to model regional chemistry under undisturbed polluted conditions. Model results suggest that changing stimulate leading enhanced ozone production greater mineral acidity rainfall colonized agricultural regions. agree with measurements made during NASA ABLE missions. Under agricultural/pastoral scenarios, regions export levels N2O, CH4, CO, photochemical precursors NOy O3 global atmosphere implications for climatic warming.
