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.

AER_RTAPLAND provides aerosol and land?surface properties over land retrieved using the RemoTAP algorithm. Because RemoTAP jointly models surface and atmosphere over land, the suite also provides spectrally resolved land-surface BRDF and BPDF parameters for reflectance and polarization. Typical uses: air-quality and climate studies, aerosol context for ocean-color/land analyses, radiative transfer, and model evaluation.

AER_RTAPOCEAN provides aerosol optical/microphysical properties retrieved over the oceans, along with coupled surface parameters used in the retrieval. The suite includes spectral aerosol optical depth (AOD), single-scattering albedo (SSA), complex refractive index (real/imaginary), size distribution metrics (e.g., fine/coarse effective radii and fine-mode fraction), and aerosol shape/fraction spherical; it also reports ocean surface roughness (glint/wind parameterization) and “ocean body” properties that define the water-leaving signal for consistency with the coupled atmosphere–ocean inversion. Use AER_RTAPOCEAN for aerosol-climate and air-quality studies, as aerosol context for ocean-color atmospheric correction, and for model evaluation and data assimilation; pair it with OCI/HARP2 products for cross-sensor analyses.
