TL;DR: In this article, the quality and accuracy of the fraction of absorbed photosynthetically active radiation (FAPAR) products generated from an analysis of Sea-viewing Wide Field-of-view Sensor (SeaWiFS) data are discussed.
Estimating forest aboveground biomass by low density lidar data in mixed broad-leaved forests in the Italian Pre-Alps
Antonio Montagnoli,Sara Fusco,Mattia Terzaghi,Alan A. Kirschbaum,Dirk Pflugmacher,Warren B. Cohen,Gabriella S. Scippa,Donato Chiatante +7 more
TL;DR: In this article, the utility of low-density lidar data for estimating forest aboveground biomass in the mountainous forests of northern Italy was investigated, and the best height results showed a R 2'='0.87' from final model and the root mean square error (RMSE) 1.02'm (8.3% of the mean).

Using object‐oriented classification and high‐resolution imagery to map fuel types in a Mediterranean region
TL;DR: Results suggested that object-oriented classification of high-resolution imagery has the potential to create accurate and spatially precise fuel maps.
Decadal trends in net ecosystem production and net ecosystem carbon balance for a regional socioecological system
David P. Turner,William D. Ritts,Zhiqiang Yang,Robert E. Kennedy,Warren B. Cohen,Maureen V. Duane,Peter E. Thornton,Beverly E. Law +7 more
TL;DR: In this paper, a combination of remote sensing and ecosystem modeling is used to examine the trends in NEP and net ecosystem carbon balance (NECB) in this region over the 1985-2007 period, with particular attention to land ownership since management now differs widely between public and private forestland.
