ACIX III Land Results

Across the 90 scenes used in this exercise, the SR algorithms tested showed average uncertainty values between 0.02 and 0.04, depending on wavelength and sensor. For AOD retrieval, half of the algorithms had uncertainties below 0.1, while some algorithms had issues due to the reliance on dark pixels. Finally, WV retrievals showed good results with some consistent offsets, showing uncertainty values between 0.17 and 0.88 g/cm2.
