Anisotropic Radiance/Reflectance Simulations for Clouds

This data file contains anisotropic (sensor viewing azimuth angles range from 0 to 360° of every 5°) radiance and reflectance calculations at the top of the atmosphere for clouds. Radiative transfer parameters: 1) sensor viewing zenith angle of 45°; 2) solar zenith angle of 60°; 3) solar azimuth angle of 0 (north); 4) surface albedo (Lambertian): 0.03; 5) cloud optical thickness: 10; 6) cloud effective radius: 12 micron; 7) cloud vertical location: 0.5 km to 1 km. Data description: rad_555: 1D array (size of 73), radiance at 555 nm, units in W/m²/nm/sr; ref_555: 1D array (size of 73), reflectance at 555 nm; rad_vis: 1D array (size of 73), broadband (350 - 700 nm) radiance, units in W/m²/nm/sr; ref_vis: 1D array (size of 73), broadband (350 - 700 nm) reflectance; vaa: 1D array (size of 73), sensor viewing azimuth angles, units in degree; vza0: single value, sensor viewing zenith angle, units in degree; saa0: single value, solar azimuth angle, units in degree; sza0: single value, solar zenith angle, units in degree. Notes: This data file is generated by the code included in EaR³T (https://github.com/hong-chen/er3t, function <example_rad_02_libera_adm> in <examples/00_er3t_lrt.py>). The listed parameters such as solar and sensor viewing geometries, cloud optical properties, surface albedo etc. can be customized.
