Correlation Analysis between Atmospheric Transmittance and Observed Brightness Using Ground-Based Satellite Tracking Data

This study investigates the correlation between atmospheric transmittance and observed brightness using satellite tracking data collected from a ground-based observation station. Atmospheric transmittance was calculated under mid-latitude winter conditions using MODTRAN software, while observed brightness was derived from satellite tracking data independently of transmittance measurement angles. Polynomial regression was applied to model the relationship between transmittance and brightness. The results allowed for a quantitative assessment of the impact of atmospheric conditions on satellite brightness across various elevation angles. This study provides foundational insights for satellite observation by clarifying the relationship between atmospheric transmittance and brightness changes under specific observational conditions. Future work may expand upon these findings by exploring a broader range of seasonal and environmental factors to enhance the generalizability of the model.
