Supporting a Forest Observation System for Siberia: Earth Observation for Monitoring, Assessing and Providing Forest Resource Information

EarthzineEcosystems, Original

he monitoring and assessment of the remote Russian forest resources of Siberia is challenging and can only be done by integrating remote sensing techniques. Human and environmental forest disturbances continuously affect changing forest cover and biomass levels. The ZAṔS initiative is prototyping and supporting a forest observation system for Siberia using Earth observation data from European and Russian satellite data providers.

The paper proposes a new approach to estimating live fuel moisture content, a key variable in fire danger assessment. Our proposed model uses an alternative inversion procedure based on the look-up table technique. The model outperforms already-published Mediterranean models in estimated moisure content in the temperate grassland and shrubland of Spain‰Ûªs Eurosiberian ecosystem.
