7/13/11Runze Li, a professor of statistics at Penn State, has been honored with the Norbert Gerbier-MUMM International Award for 2012 for a paper written with co-authors from other institutions spanning six continents. The paper, "Climate control of terrestrial carbon exchange across biomes and continents," which was published in Environmental Research Letters, examines relationships between climate and the carbon exchange of land-based ecosystems to predict future levels of atmospheric carbon dioxide. Li, who is the only statistician among the 151 authors of this paper, used the statistical techniques known as mixture regression and two-dimensional kernel regression to analyze the data presented in the paper. The purpose of the Norbert Gerbier-MUMM International Award, which is presented by the World Meteorological Organization, a specialized agency of the United Nations, is "to encourage and reward annually an original scientific paper on the influence of meteorology in a particular field of the physical, natural, or human sciences, or on the influence of one of these sciences on meteorology."
