Thermophysical Assessment of High-Albedo Surfaces for Solar Radiation Management and Equivalent Energy Impact Evaluation

The modification of surface radiative properties has been increasingly examined from the perspective of engineering thermophysics, particularly in relation to solar radiation management and its impact on surface energy balance. In this study, a methodological framework, referred to as the radiative forcing (RF)-meter, is introduced to quantify the RF variation induced by high-albedo surfaces under real environmental conditions. The proposed approach integrates ground-based irradiance measurements, astronomical calculations, and satellite observations to reconstruct the time-dependent radiative flux associated with albedo changes. Based on this formulation, the reduction in absorbed solar energy is evaluated and further interpreted in terms of equivalent energy impact, providing a consistent basis for linking radiative effects with thermophysical processes. The framework also allows the cumulative effect of RF reduction to be expressed in CO -equivalent terms, enabling a quantitative interpretation of long-term environmental and energy-related implications. Potential applications of the method are discussed with reference to high-irradiance regions, where surface reflectivity modification may contribute to both thermal regulation and energy demand reduction. The proposed methodology offers a structured approach for analysing surface energy behaviour within the context of engineering thermophysics, with possible extensions toward building energy efficiency and solar radiation control strategies.
