Journal ArticleDOI
Calibration and validation of hyperspectral indices for the estimation of broadleaved forest leaf chlorophyll content, leaf mass per area, leaf area index and leaf canopy biomass
Guerric Le Maire,C. François,Kamel Soudani,Daniel Berveiller,Jean-Yves Pontailler,Nathalie Bréda,Hélène Genet,Hendrik Davi,Eric Dufrêne +8 more
TL;DR: In this paper, the authors proposed a hyperspectral indices for the estimation of forest sun leaf chlorophyll content (CHL, µg cm leaf −2 ), sun leaf mass per area (LMA, g dry matter m leaf − 2 ), canopy leaf area index (LAI, m 2 leaf m soil − 2 ) and leaf canopy biomass (B leaf, g dry material m soil−2 ).
Journal Article
Calibration and validation of hyperspectral indices for the estimation of broadleaved forest leaf chlorophyll content, leaf mass per area, leaf area index and leaf canopy biomass
G. Le Maire,C. François,Kamel Soudani,Daniel Berveiller,Jean-Yves Pontailler,Nathalie Bréda,Hélène Genet,Hendrik Davi,Eric Dufrêne +8 more
TL;DR: In this article, the best vegetation indices (index form and wavelengths) were determined on a generic simulated database to estimate CHL, LMA, LAI and Bleaf in a general way.

TL;DR: In this paper, the authors synthesize regional in situ observations of CO2 flux from Arctic and boreal soils to assess current and future winter carbon losses from the northern permafrost domain.
Journal ArticleDOI
Age-related variation in carbon allocation at tree and stand scales in beech (Fagus sylvatica L.) and sessile oak (Quercus petraea (Matt.) Liebl.) using a chronosequence approach
TL;DR: The hypothesis that growth decrease related to age is accompanied by changes in carbon allocation to the benefit of storage and reproductive functions in two contrasting broad-leaved species, beech and sessile oak, is tested.
Journal ArticleDOI
The effects of fire on the thermal stability of permafrost in lowland and upland black spruce forests of interior Alaska in a changing climate
Elchin Jafarov,Elchin Jafarov,Vladimir E. Romanovsky,Hélène Genet,A. D. McGuire,Sergey Marchenko +5 more
TL;DR: In this paper, the authors evaluated the sensitivity of permafrost to climate, burn severity, soil organic layer thickness, and soil moisture content in lowland and upland black spruce ecosystems.
