The potential of ALOS single polarization INSAR for estimation of growing stock volume in Boreal forest

This paper present the main results from an investigation of the potential of L-band coherence from ALOS PALSAR for estimation of growing stock volume. The work has been limited to the boreal biome zone where two forest territories in central Siberia have been selected as test regions. 18 coherence images from repeat-pass acquisitions with ALOS predecessor JERS have been used for the analysis. The results indicate that growing stock volume estimation should be possible with PALSAR repeat pass coherence using only the HH polarization. Seasonal limitations have been identified and show that repeatpass acquisitions should be avoided during periods of freeze and thaw. The most promising results are obtained from the winter season.
