PACE SPEXone Level-3 Global Mapped Aerosol Optical Properties, RemoTAP Algorithm Data, version 4.0

AER_RTAP provides aerosol properties retrieved using the RemoTAP algorithm. The suite includes variables for characterizing aerosol loading, size, and absorption. Use AER_RTAP for air-quality and climate studies, aerosol context for ocean-color atmospheric correction, and model evaluation. Geophysical variables in this suite include: • angstrom_440_670 — Aerosol Ångström exponent, 440–670 nm (unitless) • aot — Aerosol optical thickness (unitless) • fmf — Aerosol fine mode fraction (unitless) • fvf — Aerosol fine mode volume fraction (unitless) • lidar_bsca_total — Aerosol lidar backscatter coefficient (sr⁻¹ m⁻¹) • lidar_depol_ratio — Aerosol lidar depolarization ratio (unitless) • lidar_p11_pi — Aerosol phase function p11 at backscatter direction (unitless) • mi — Aerosol refractive index, imaginary part (unitless) • mr — Aerosol refractive index, real part (unitless) • reff_coarse — Aerosol effective radius, coarse mode (µm) • reff_fine — Aerosol effective radius, fine mode (µm) • ssa — Aerosol single scattering albedo (unitless)
