1 Abstract— We present results from experiments carried out in the GB-SAR facility at the University of Sheffield to ascertain the role of polarimetric interferometry in crop height retrieval. To this end, a mature wheat canopy, grown in outdoor conditions, was reassembled inside the GB-SAR chamber and imaged at C-band using a two-dimensional scan. This(More)
Physically-based radiative transfer models (RTMs) help in understanding the processes occurring on the Earth's surface and their interactions with vegetation and atmosphere. However, advanced RTMs can take a long computational time, which makes them unfeasible in many real applications. To overcome this problem, it has been proposed to substitute RTMs(More)
This study explores the capability of satellite remote sensing to detect relatively rapid changes of vegetation cover in northern Fennoscandian regions in response to disturbance more generally, and insect defoliation damage in particular. The data used is a long term time series of leaf area index (LAI) at 8Km resolution derived from the Advanced Very High(More)
This paper presents a method to extract information on the impact of wildfire on vegetation canopies. A simple linear model is proposed with a 'generic' spectral model of the impacts of wildfire on vegetation canopies. This allows a term related to the projected proportion of a pixel affected by fire (fcc) to be estimated from measurements of pre-and(More)
