The global mean of aerosol optical depth at 550 nm over land is ~0.19 and over oceans is ~0.13. About 45% of the Earth surface shows AOD at 550 nm smaller than 0.1. Hence, there is a need for measurement techniques that are optimized to measure aerosol optical properties under low AOD conditions. Over the past decade the multi-axis differential optical
