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.

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.
