The 2015–2016 El Niño-induced drought caused biomass loss in global tropical forests, yet the recovery duration of different vegetation components (woody components, upper canopies, and leaves) remains unknown. Here, we use satellite remote sensing data optical depth leaf area index, with varying sensitivity to examine during event. We find that woody component had slowest compared canopy leaves, displayed greater spatial variability between continents. Key factors influencing include severity, moisture-related climatic conditions (i.e., vapor pressure deficit, precipitation, soil moisture), seasonal variations temperature precipitation. Our study highlights importance for maintaining ecosystem balance under disturbances indicates need further research explore mechanisms long-term impacts on forest dynamics. Woody forests have a slower rate from severe canopies according multiple observations across tropics 2015-2016
