The new subroutines were developed by Dr. The spectral response curves for all these instruments can be found in the 6S manual, version 3. Several new subroutines, simulating measurements of the ALI, ASTER, ETM, HYPBLUE, VGT, and VIIRS instruments, have been integrated into the the vector 6S.Default exponential vertical aerosol profile.Fixed number of calculation layers (26) and angles (48).SVE provides 32 scalable vector registers, named Z0 - Z31. ![]() Fixed number of scattering angles (83), used for the specification of an aerosol phase function. Vector code allows each implementation to automatically choose its vector length, provided it is a multiple of 128 bits and does not exceed the architectural maximum of 2048 bits.Scalar (ignoring the effects of polarization).The code is based on the method of successive orders of scatterings approximations and its first vector version (6SV1), capable of accounting for radiation polarization. It enables accurate simulations of satellite and plane observation, accounting for elevated targets, use of anisotropic and lambertian surfaces and calculation of gaseous absorption. The 6S code is a basic RT code used for calculation of lookup tables in the MODIS atmospheric correction algorithm.
