PhD student Chi Chen co-authors article on 2015/16 ENSO event impacts to the carbon cycle

October 22nd, 2018 in 2018, Faculty, Graduate students, Oct-18, Ranga Myneni

PhD student Chi Chen (advised by Ranga Myneni) contributed to a recently published article on the impacts of 2015/16 El Niño event to the terrestrial Carbon cycle. In “Impact of the 2015/2016 El Niño on the terrestrial carbon cycle constrained by bottom-up and top-down approaches,” published in Philosophical Transactions of the Royal Society, Chen and his colleagues note this major event imposed extreme warming and dryness in the tropics and other sensitive regions causing a significant perturbation to the global carbon cycle.

PhD alum Yan Yang publishes in Nature Communications

September 6th, 2018 in 2018, Faculty, Former Students, Pub-18, Publications, Ranga Myneni, Sept-18

Yan Yang, a 2017 PhD graduate, recently published part of her dissertation research in Nature Communications. In “Post-drought Decline of the Amazon Carbon Sink” Yang and her colleagues report a significant loss of carbon over the entire Amazon basin at a rate of 0.3 +/- 0.2 PgC per year after the 2005 mega-drought, which continued persistently over the next three years (2005-2008) using systematic sampling of forest structure measured by LIDAR waveforms. Dr. Yang is affiliated with UCLA’s Institute of the Environment and Sustainability.

Visiting Scholar Dr. Kai Yan from Beijing Normal University and Mr. Baodong Xu from the Institute of Remote Sensing and Digital Earth, Beijing, published three articles on the physics and implementation of LAI/FPAR algorithm for the NASA’s Suomi VIIRS sensor and an evaluation of the derived product. The articles are in collaboration with PhD students Taejin Park and Chi Chen in Professor Ranga Myneni’s research group.

PhD student Chi Chen and Prof. Myneni coauthor paper in Nature Sustainability

January 26th, 2018 in 2018, Faculty, Graduate students, Jan-18, News, Pub-18, Publications, Ranga Myneni

A paper coauthored by PhD student Chi Chen and Professor Ranga Myneni entitled “Increased vegetation growth and carbon stock in China karst via ecological engineering” was recently published in the inaugural issue of Nature Sustainability.

The paper describes the use of MODIS LAI data and show a widespread increase in leaf area index (a proxy for green vegetation cover), and aboveground biomass carbon. In spite of drought conditions, aboveground biomass carbon increased by 9% (+0.05 Pg C y−1), mainly in areas of high conservation effort. The authors conclude that large scale conservation projects can contribute to a greening Earth with positive effects on carbon sequestration to mitigate climate change.

A News & Views item describing the article to the general public appeared in Nature.

Prof. Myneni coauthors paper in Nature Ecology and Evolution

January 12th, 2018 in 2018, Faculty, Jan-18, News, Pub-17, Publications, Ranga Myneni

A paper coauthored by Professor Ranga Myneni entitled “Velocity of change in vegetation productivity over northern high latitudes” was recently published in Nature Ecology and Evolution. The paper compares changes in the spatial patterns of vegetation productivity and temperature using the velocity of change concept, which expresses these two variables in the same unit of displacement per time.

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
