Implication

Remote sensing analysis demonstrates that airborne LiDAR calibration enhances tropical forest carbon density mapping accuracy, highlighting cost-effective strategies for national monitoring.

Key Points

To determine whether integrating airborne high-resolution LiDAR samples with moderate-resolution remote sensing data improves the accuracy and detail of regional aboveground carbon density mapping.
Integrated high-resolution airborne LiDAR samples to fine-tune freely available moderate-resolution satellite remote sensing imagery.
Evaluated model performance and calibration across tropical forest regions in the Peruvian and Colombian Amazon against existing pantropical datasets.
Existing pantropical datasets explained approximately 70% of variance in aboveground carbon density relative to high-resolution LiDAR estimates.
Regional calibration with airborne LiDAR reduced relative root mean squared error from 25.2 to 15.7 MgC ha⁻¹ in Colombia and from 31.4 to 17.6 MgC ha⁻¹ in Peru.
