Description:
Volcanic aerosols from the 1991 Mount Pinatubo eruption greatly increased diffuse radiation worldwide for the following 2 years. We estimated that this increase in diffuse radiation alone enhanced noontime photosynthesis of a deciduous forest by 23% in 1992 and 8% in 1993 under cloudless conditions. This finding indicates that the aerosol-induced increase in diffuse radiation by the volcano enhanced the terrestrial carbon sink and contributed to the temporary decline in the growth rate of atmospheric carbon dioxide after the eruption.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Lianhong -- Baldocchi, Dennis D -- Wofsy, Steve C -- Munger, J William -- Michalsky, Joseph J -- Urbanski, Shawn P -- Boden, Thomas A -- New York, N.Y. -- Science. 2003 Mar 28;299(5615):2035-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental Sciences Division, Building 1509, Oak Ridge National Laboratory, Oak Ridge, TN 37831-6335, USA. lianhong-gu@ornl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12663919" target="_blank"〉PubMed〈/a〉
