Forest biomass change estimated from height change in interferometric SAR height models [PDF]
Carbon Balance and Management, 2014 There is a need for new satellite remote sensing methods for monitoring tropical forest carbon stocks. Advanced RADAR instruments on board satellites can contribute with novel methods. RADARs can see through clouds, and furthermore, by applying stereo RADAR imaging we can measure forest height and its changes.

Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]
, 2005 The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

Forest typological structure of oak forests of volyn height
Forestry, Forest, Paper and Woodworking Industry, 2018 Oak (Quercus robur L.) is one of the most common and valuable tree species in the Western Forest-Steppe of Ukraine. Much of the oak forests of the Western Forest-Steppe are concentrated in the forest district of Volyn Upland, which, despite belonging to the Western Ukrainian Forest-Steppe Forest District, is characterized by special geomorphological ...

Uncertainties and Perspectives on Forest Height Estimates by Sentinel-1 Interferometry
Earth, 2022 Forest height is a key parameter in forestry. SAR interferometry (InSAR) techniques have been extensively adopted to retrieve digital elevation models (DEM) to give a representation of the continuous variation of the Earth’s topography, including forests.
