Ranga Myneni named a Highly Cited Researcher by Thomson-Reuters

June 11th, 2014 in 2014, Awards, Faculty, June-14, News, Ranga Myneni

Earth & Environment Professor Ranga Myneni was recently selected to the list Highly Cited Researchers 2014 by Thomson-Reuters.

In creating the list, Thomson-Reuters collected data on articles indexed in the Web of Science Core Collection from 2002 to 2012, selecting only articles that were labeled as Highly Cited Papers. As their website explains, “Highly Cited Papers are defined as those that rank in the top 1% by citations for field and year indexed in the Web of Science.” This process, they claim, eliminated “the citation disadvantage of recently published papers relative to older ones, since papers are weighted against others in the same annual cohort.”

Researchers were then selected and ranked based on the number of  ”citations to his or her Highly Cited Papers to rank in the top 1% by total citations in the ESI field in which they were considered.” The Essential Science Indicators, or ESI, fields are “21 broad fields defined by sets of journals and exceptionally, in the case of multidisciplinary journals such as Nature and Science, by a paper-by-paper assignment to a field.”

Their selection process yielded the top 1% of researchers in 21 different scientific fields.

Myneni was selected in the top 1% of researchers in the field of geosciences. He was one of nine Boston University researchers included on the list and the only Boston University selection in the field of geoscience.

Ranga Myneni coauthors an article in the journal “Proceedings of the National Academy of Sciences USA”

February 14th, 2014 in 2014, 2014, Faculty, February-14, Publications, Ranga Myneni

Department of Earth and Environment Professor Ranga Myneni coauthored a paper in the journal PNAS.

The paper “Afforestation in China cools local land surface temperature” was published on February 10th, 2014 and is a collaborative activity between researchers in China, France, and the USA. The paper reports the finding that afforestation decreases daytime land surface temperature (LST), because of enhanced evapotranspiration, and increases nighttime LST. This nighttime warming tends to offset daytime cooling in dry regions. These results suggest that it is necessary to carefully consider where to plant trees to achieve potential climatic benefits in future afforestation projects.

Professor Terry Callaghan of the University of Sheffield in the United Kingdom presented the findings of former Graduate Student Xu Liang and Department of Earth and Environment Professor Ranga Myneni to the King of Sweden as part of the Royal Colloquium convened roughly every two years by His Majesty King Carl XVI Gustaf.

The topics of the Royal Colloquium usually focus on environmental issues of global importance; this year’s theme was “A Changing World: Redrawing the Map,” and it was held at the Abisko Scientific Research Station in the Swedish sub-Arctic and at the Royal Palace in Stockholm.

Prof. Callaghan presented a talk titled “Arctic climate change: mismatches in expectations among the players and possible consequences” as part of the Colloquium and included examples of climate change impacts from Liang’s 2013 Nature Climate Change paper, “Temperature and vegetation seasonality diminishment over northern lands,” in his talk.

Prof. Callaghan, who was also a coauthor on Liang’s 2013 paper, was presented the prestigious Vega Medal in 2011 by His Majesty.
