Yuri Knjazihhin awarded new NASA grant

September 5th, 2014 in 2014, Faculty, Grants, Juri Knjazihhin, Ranga Myneni, Sept-14

Earth & Environment Professor Yuri Knjazihhin was awarded a new NASA Grant titled “Earth System Data Records of Global Vegetation Index, Fraction of Absorbed PAR, Leaf Area and its Sunlit Fraction from DSCOVR data” under the NASA DSCOVR Earth Science Algorithms Program.

The objective of this three year proposal is to develop Earth System Data Records of global Fraction vegetation absorbed Photosynthetically Active Radiation (FPAR), Leaf Area Index (LAI) and its sunlit fraction (SLAI), and Normalized Difference Vegetation Index (NDVI) from the Earth Polychromatic Imaging Camera (EPIC) data.

A special emphasis will be given to achieving consistency and complementarity between DSCOVR EPIC and existing NASA land surface products.

Earth & Environment Professor Ranga Myneni is co-investigator.

Earth & Environment Professor Ranga Myneni was awarded a new NASA Grant titled “Global LAI-FPAR Earth System Data Records from Suomi VIIRS to Extend the EOS MODIS Time Series” under the NASA Suomi VIIRS Science Team Program. The objective of this three year grant is to provide and maintain the algorithm for operational production of global LAI/FPAR science data records by the NASA Suomi NPP Land SIPS from Suomi VIIRS data and to evaluate these products to assure continuity with the EOS MODIS product time series. A list of Myneni’s grants can be found at http://sites.bu.edu/cliveg/projects/active-projects/

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.
