“…One hundred and twenty-two ERS SAR tandem pairs were processed using the interferometry software of the German Remote Sensing Data Center, Wesseling, Germany (Roth, Knöpfle, Hubig, & Adam, 1998). With few exceptions, tandem pair data acquired during fall 1997 were used.…”

Siberia's boreal forests represent an economically and ecologically precious resource, a significant part of which is not monitored on a regular basis. Synthetic aperture radars (SARs), with their sensitivity to forest biomass, offer mapping capabilities that could provide valuable up-to-date information, for example about fire damage or logging activity. The European Commission SIBERIA project had the aim of mapping an area of approximately 1 million km 2 in Siberia using SAR data from two satellite sources: the tandem mission of the European Remote Sensing Satellites ERS-1/2 and the Japanese Earth Resource Satellite JERS-1. Mosaics of ERS tandem interferometric coherence and JERS backscattering coefficient show the wealth of information contained in these data but they also show large differences in radar response between neighbouring images. To create one homogeneous forest map, adaptive methods which are able to account for brightness changes due to environmental effects were required. In this paper an adaptive empirical model to determine growing stock volume classes using the ERS tandem coherence and the JERS backscatter data is described. For growing stock volume classes up to 80 m 3 /ha, accuracies of over 80% are achieved for over a hundred ERS frames at a spatial resolution of 50 m. D

“…The important ERS system parameters for the calculations are listed in gure 1. In the processing of the coherence (Roth et al 1998), co-registration of the SLC image pair was achieved within 0.05-0.3 pixels depending on topography . This ensured a negligible loss of coherence caused by misregistration errors.…”

In this study, changes in the temporal and volume contributions (|c | temporal , |c| volume ) to the observed ERS-1/2 coherence are modelled in response to an increase of forest woody biomass in Central Siberia. It is demonstrated that the distance between neighbouring trees and the vertical structure of boreal forest canopies must be accounted for to model |c| volume . Results con rm that |c| temporal is the main decorrelation factor although |c| volume contributes signi cantly to the overall loss of coherence observed over mature forests.

“…The German Remote Sensing Data Center (DFD) developed an interferometric processing system mainly designed for the operational derivation of digital elevation models (DEMs) from space borne synthetic aperture radar (SAR) systems such as European Space Agency (ESA) Remote Sensing Satellite (ERS), Shuttle Radar Topography Mission (SRTM) and Envisat Advanced Synthetic Aperture Radar (ENVISAT-ASAR) (Roth et al, 1998). It consists of a line of processors allowing the ingestion of different SAR input products at different preprocessing levels.…”
