Abstract

Abstract

En 中文
• TECIS captures post-fire vertical forest structure differences at the footprint-level. • RH75–RH95 declines indicate pronounced mid- and upper-canopy collapse in burned stands. • Burned forests show 41–53% lower AGB across coniferous, mixed, and broadleaf stands. • Integration with Sentinel data enables scalable mapping of post-fire forest structure and biomass. • Independent validation with 108 plots supports the final AGB map (R2 = 0.64; rRMSE = 34.71%).
