Impacts of using solar spectra adjusted for solar cycle variability in the radiometric correction of retrieved multi-band parameters from ETM+/Landsat-7 data

Key Points

• Retrieved multi-band parameters are affected by variations in solar spectra, impacting data accuracy greatly.
• During solar cycles, changes in solar activity influence the stability of parameters over time, leading to inaccuracies in measurements.
• Analysis using Landsat-7 data highlights the need for adjusted radiometric correction methods to account for solar variability.
• Understanding these effects may enable better calibration techniques for remote sensing applications using multi-band imagery.
