Prof. Myneni co-authors papers in Nature Climate Change

June 12th, 2017 in 2017, Faculty, Jun-17, News, Pub-17, Publications, Ranga Myneni

Professor Ranga Myneni has co-authored two papers in Nature Climate Change.

One describes how the greening of the Earth, largely due to CO2 fertilization, has also increased evapo-transpiration and thus cooled the planet. https://www.nature.com/nclimate/journal/v7/n6/full/nclimate3299.html

The second  describes the weakening relationship between temperature and spring carbon uptake in the recent years. These two recent papers from this group of authors are of a larger body of work on the biophysical and biochemical effects of a greening Earth. https://www.nature.com/nclimate/journal/v7/n5/full/nclimate3277.html

Prof. Myneni and former visiting scholar Zhu author one of top 10 climate change papers of 2016

February 7th, 2017 in 2017, Awards, Faculty, Feb-17, News, Pub-16, Publications, Ranga Myneni, Researchers

A paper entitled “Greening of the Earth and its Drivers” published in the journal Nature Climate Change in April 2016 has made it into the top 10 climate change articles of 2016. The first author Zaichun Zhu was a Visiting Scholar in Prof. Myneni’s research group. Details can be found here, and the full article can be found here.

Professor Ranga Myneni co-authors article in PNAS

November 4th, 2016 in 2016, Faculty, Nov-16, Pub-16, Publications, Ranga Myneni

Earth and Environment Professor Ranga Myneni recently coauthored an article titled “Reducing uncertainties in decadal variability of the global carbon budget with multiple datasets” in the journal Proceedings of the National Academy of Sciences of the USA. Conventional approaches of calculating the global carbon budget makes the land sink the most uncertain of all budget terms. This is because, rather than being constrained by observations, it is inferred as a residual in the budget equation. In this article, the authors overcome this limitation by performing a Bayesian fusion of different available observation-based estimates of decadal carbon fluxes. This approach reduces the uncertainty in the land sink by 41% and in the ocean sink by 46%. These results are significant because they give unprecedented confidence in the role of the increasing land sink in regulating atmospheric CO2, and shed light on the past decadal trend.

PhD student Sungho Choi publishes dissertation research in Global Ecology and Biogeography

September 26th, 2016 in Graduate students, Pub-16, Ranga Myneni, Sept-16

PhD student Sungho Choi recently published his dissertation research in the journal Global Ecology and Biogeography. Entitled “Application of the metabolic scaling theory and water–energy balance equation to model large-scale patterns of maximum forest canopy heights,” the article describes refinements to a model called Allometric Scaling and Resource Limitations (ASRL), accounts for the size-dependent metabolism of trees whose maximum growth is constrained by local resource availability. The article can be downloaded at http://onlinelibrary.wiley.com/doi/10.1111/geb.12503/pdf.

Mr. Choi was a Fulbright Scholar and a recipient of the NASA Graduate Fellowship. He hopes to defend his dissertation during the fall 2016 term. His PhD supervisor is Prof. Myneni.

PhD student Taejin Park publishes dissertation research article in ERL

September 14th, 2016 in Graduate students, Pub-16, Publications, Ranga Myneni, Sept-16

PhD student Taejin Park recently published his ongoing dissertation research in an article in the journal Environmental Research Letters. Entitled “Changes in growing season duration and productivity of northern vegetation inferred from long-term remote sensing data,” the article describes three decades of changes in northern vegetation activity and is part of an ERL special issue on Focus on Recent, Present and Future Arctic and Boreal Productivity and Biomass Changes. The article can be downloaded here.

Mr. Park is a recent NASA Graduate Fellowship winner and is in his third year of PhD studies with Prof. Myneni.

Prof. Prof. Rautiainen and Dr. Mottus visit Earth & Environment’s Myneni & Knyazikhin Research Group

September 14th, 2016 in Faculty, Juri Knjazihhin, News, Ranga Myneni, Sept-16

Prof. Miina Rautiainen of the University of Aalto (Finland) and Dr. Matti Mottus of VTT Technical Research Center of Finland are visiting Profs. Myneni-Knyazikhin research group for three weeks in September. Our collaborative research includes design of field studies, validation of satellite LAI and FPAR products, and radiative transfer theory for remote sensing of vegetation.

Prof. Myneni co-authors article in Nature Climate Change

August 16th, 2016 in August 2016, News, Pub-16, Publications, Ranga Myneni

A research article titled “Human-induced greening of the northern extratropical land surface” was published this week in the journal Nature Climate Change. The paper reports that the observed greening record is consistent with an assumption of anthropogenic forcings, where greenhouse gases play a dominant role, but is not consistent with simulations that include only natural forcings and internal climate variability. The paper can be downloaded from the journal, and a lay man’s description of this work and its significance can be found in a recent news item from the Washington Post.
