Land: retrieval of optical thickness and UV surface albedo (only UV bands are used). PMD calibration is expected to improve Figure: Estimated standard deviation in the optical thickness retrieved from the science channel intensity measurements (dashed line) and from the PMDs (solid line) as a function of solar zenith angle (SZA).
