The upcoming BIOMASS mission will provide P-band repeat-pass PolInSAR data from space for the improved mapping of global biomass. PolInSAR technique has been widely validated with the potential to invert forest height and estimate forest aboveground biomass (AGB). However. the robustness of PolInSAR-based AGB estimation across different sites still lacks full evaluation. https://fitnessgravesyardes.shop/product-category/guard/
