Short Summary

This paper introduces a stepwise Bidirectional Reflectance Distribution Function (BRDF) model designed to accurately estimate land surface reflectance in areas characterized by rugged terrain.

Objective

• To develop and evaluate a novel stepwise Bidirectional Reflectance Distribution Function (BRDF) model specifically tailored for land surface reflectance estimation over rugged terrain.

Study Configuration

• Spatial Scale: Focuses on areas with complex topography ("rugged terrain"), implying applications from local to regional scales.
• Temporal Scale: Addresses land surface reflectance, which typically involves instantaneous or short-term measurements, but no specific temporal resolution is provided.

Methodology and Data

• Models used: A novel "stepwise BRDF-based land surface reflectance model" is the core methodology.
• Data sources: Not specified, but would typically involve remote sensing data (e.g., satellite imagery) providing multi-angular reflectance measurements.
