Fire event (Pearsoll Peak, CA) FAPAR September 2002 Long Time series of 10-day Active Fire Detection 2002 The FAPAR values suddenly decline after the 2002 summer fire events and keep low values, by comparison to those obtained for the period 1998-2001, until the end of 2003. The 2003 FAPAR estimations suggest that the vegetation has not recovered from the 2002 fire stress. Gobron N., et. al. (2006) ‘Evaluation of FAPAR Products for Different Canopy Radiation Transfer Regimes: Methodology and Results using JRC Products Derived from SeaWiFS and Ground-based Estimations', JGR, DOI 10.1029/2005JD006511 80
Rice (Pavia, IT) FAPAR July 2003 Long Time series of 10-day The FAPAR values are stable over all years. The 2003 FAPAR estimations suggest that the growth period was in advance comparing to a normal year. Gobron N., et. al. (2006) ‘Evaluation of FAPAR Products for Different Canopy Radiation Transfer Regimes: Methodology and Results using JRC Products Derived from SeaWiFS and Ground-based Estimations', JGR, DOI 10.1029/2005JD006511 81
