SSARA A-LIFE measurement data

This dataset contains the measurement data of the SSARA-P polarized sun and sky photometer during the A-LIFE field campaign in Cyprus during April 2017. The data is provided in several stages of preprocessing: <em>L0</em>: raw instrument data <em>L1</em>: calibrated measurements <em>L2</em>: Aerosol Optical Thickness (AOT) derived from direct sun measurements The datasets are also split for three different observation geometries: <em>direct</em>: direct sun observation <em>almuc</em>: almucantar geometry (scan at solar elevation) <em>pplane</em>: principle plane scan (hemispheric scan through sun and zenith)
