Second year PhD student Chi Chen published his first research article entitled “Prototyping of LAI and FPAR Retrievals from MODIS Multi-Angle Implementation of Atmospheric Correction (MAIAC) Data” in the open source journal Remote Sensing. Mr. Chen is advised by Profs. Knyazikhin and Myneni. The article can be downloaded here.
Prof. Prof. Rautiainen and Dr. Mottus visit Earth & Environment’s Myneni & Knyazikhin Research Group
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.
More information about the project, Prof. Rautianen, and Dr. Mottus can be found at:

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 PhD student Taejin Park published an article in the journal Remote Sensing. The article is titled “Application of physically-based slope correction for maximum forest canopy height estimation using waveform lidar across different footprint sizes and locations: Tests on LVIS and GLAS.” The article can be downloaded from http://www.mdpi.com/2072-4292/6/7/6566
