PACE OCI Level-3 Global Mapped Aerosol Optical Properties, Unified Aerosol Algorithm (UAA) Algorithm Data, version 3.1

Core variables include measures that describe aerosol loading, size partitioning, and absorption. A companion product in the same family provides the UV Absorbing Aerosol Index (UVAI_UAA).

Typical uses include air-quality and climate analyses, aerosol context for ocean-color atmospheric correction, trend studies, and model evaluation; users should refer to per-file metadata/flags for quality screening and wavelength availability. Core geophysical variables in this suite include: - Aerosol_Optical_Depth_λ - Aerosol optical thickness at λ nm - NUV_AerosolIndex — Near-UV aerosol index (unitless) - NUV_AerosolOpticalDepthOverCloud — Near-UV aerosol optical depth over cloud (unitless) - NUV_CloudOpticalDepth — Near-UV cloud optical depth (unitless)
