资源简介：
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.
Core geophysical variables in this suite include:
• alh — Aerosol layer height (km)
• angstrom_440_670 / angstrom_440_870 / angstrom_490_670 — Aerosol Ångström exponents (unitless)
• aot / aot550 / aot_fine / aot_coarse — Aerosol optical thickness (unitless)
• bpdf_scale, ross_thick, li_sparse, snow_coef — BRDF/BDPF kernel coefficients (unitless)
• chla — Chlorophyll-a concentration (mg m⁻³)
• fmf / fvf — Aerosol fine mode fraction and fine mode volume fraction (unitless)
• lidar_bsca_total / lidar_depol_ratio / lidar_ratio — Aerosol lidar diagnostics (sr⁻¹ m⁻¹, unitless)
• mi / mr — Aerosol refractive index (imaginary/real part, unitless)
• reff_fine / reff_coarse — Aerosol effective radius (µm)
• sph — Aerosol spherical fraction (unitless)
• ssa — Aerosol single scattering albedo (unitless)
• vd / veff_fine / veff_coarse — Aerosol volume density (µm³ µm⁻²) and effective variance (unitless)
• waterfrac_inland — Water fraction for inland pixels (unitless)
• wind_speed — Ocean surface wind speed (m s⁻¹)
