Mapping and monitoring peatland soil moisture using drone-borne Ground-Penetrating Radar

The moisture status of peatlands is an important factor as it directly affects carbon dynamics. Therefore, it is critical to characterize and understand peatland moisture status and to monitor its spatial and temporal variations. This study aims to evaluate the potential of drone-borne ground-penetrating radar (GPR) in combination with full-wave ...
