• closedAccess   Canopy spectral invariants, Part2: Application to classification of forest types from hyperspectral data 

      Schull, Mitchell A.; Knyazikhin, Yuri; Xu, Lan; Samanta, Arun; Latorre Carmona, Pedro; Lepine, L.; Jenkins, J. P.; Ganguly, S.; Myneni, Ranga B. Elsevier (2011)
      Many studies have been conducted to demonstrate the ability of hyperspectral data to discriminate plant dominant species. Most of them have employed the use of empirically based techniques, which are site specific, requires ...
    • closedAccess   Hyperspectral remote sensing of foliar nitrogen content 

      Knyazikhin, Yuri; Schull, Mitchell A.; Stenberg, Pauline; Mõttus, Matti; Rautiainen, Miina; Yang, Yan; Marshak, Alexander; Latorre Carmona, Pedro; Kaufmann, Robert K.; Lewis, Philip; Disney, Mathias I.; Vanderbilt, Vern; Davis, Anthony B.; Baret, Frédéric; Jacquemoud, Stéphane; Lyapustin, Alexei; Myneni, Ranga B. National Academy of Sciences (2012)
      A strong positive correlation between vegetation canopy bidirectional reflectance factor (BRF) in the near infrared (NIR) spectral region and foliar mass-based nitrogen concentration (%N) has been reported in some temperate ...

      Latorre Carmona, Pedro; Knyazikhin, Yuri; Lewis, Philip; Disney, Mathias I.; Mõttus, Matti; Stenberg, Pauline; Rautiainen, Miina; Kaufmann, Robert K.; Marshak, Alexander; Schull, Mitchell A.; Vanderbilt, Vern; Davis, Anthony B.; Baret, Frédéric; Jacquemoud, Stéphane; Lyapustin, Alexei; Yang, Yan; Myneni, Ranga B. National Academy of Sciences (2013)
      Various physical, chemical, and physiological processes, including canopy structure, impact surface reflectance. Remote sensing aims to derive ecosystem properties and their functional relationships, given these impacts. ...
    • openAccess   Reply to Townsend et al.: Decoupling contributions from canopy structure and leaf optics is critical for remote sensing leaf biochemistry (Letter) 

      Latorre Carmona, Pedro; Knyazikhin, Yuri; Lewis, Philip; Disney, Mathias I.; Stenberg, Pauline; Mõttus, Matti; Rautiainen, Miina; Kaufmann, Robert K.; Marshak, Alexander; Schull, Mitchell A.; Vanderbilt, Vern; Davis, Anthony B.; Baret, Frédéric; Jacquemoud, Stéphane; Lyapustin, Alexei; Yang, Yan; Myneni, Ranga B. National Academy of Sciences (2013)
      Townsend et al. (1) agree that we explain the observed relationship (2) between foliar nitrogen (%N) and near-infrared (NIR) canopy reflectance is largely due to structure - i.e., structural variation due to fraction of ...
