with latest 7.4 and 7.5, command is i.atcorr in=b08 range=1,28001 elevation=dem parameters=p6s.txt out=b08_atcorr and I get reasonable results: r.info -r b08_atcorr_g74 min=0.003231863 max=255 r.info -r b08_atcorr_g75 min=0.003231863 max=255 my OS is Fedora 27 with compiler gcc (GCC) 7.2.1 20170915 (Red Hat 7.2.1-2) relevant compiler flags are -g -Wall -Wextra -Wpedantic -Wshadow -Wno-sign-compare -fno-common -fexceptions -Werror=implicit-function-declaration -Wp,-D_FORTIFY_SOURCE=2 -O3 -fno-fast-math -fno-fast-math might be important running i.atcorr through valgrind, I get lots of warnings like ==14080== Conditional jump or move depends on uninitialised value(s) ==14080== at 0x42B18D: os(float, float, float, float, float, float (&) [51][49], Gauss&, Altitude const&, GeomCond const&) (computations.cpp:831) ==14080== by 0x42E9E3: atmref(float, float, float, float, float, OpticalAtmosProperties&, Gauss&, GeomCond const&, AerosolModel const&, Altitude const&) (computations.cpp:1408) ==14080== by 0x42FCBC: discom(GeomCond const&, AtmosModel const&, AerosolModel const&, AerosolConcentration const&, Altitude const&, IWave const&) (computations.cpp:1654) ==14080== by 0x40C032: init_6S(char*) (6s.cpp:100) ==14080== by 0x405A3C: main (main.cpp:618) ... later on ==14080== Conditional jump or move depends on uninitialised value(s) ==14080== at 0x42DED8: iso(float, float, float, float, float, float (&) [3], Gauss&, Altitude const&) (computations.cpp:1262) ==14080== by 0x42F011: scatra(float, float, float, float, float, OpticalAtmosProperties&, Gauss&, GeomCond const&, Altitude const&) (computations.cpp:1578) ==14080== by 0x42FD08: discom(GeomCond const&, AtmosModel const&, AerosolModel const&, AerosolConcentration const&, Altitude const&, IWave const&) (computations.cpp:1659) ==14080== by 0x406882: pre_compute_h(float) (6s.cpp:148) ==14080== by 0x406372: process_raster (main.cpp:369) ==14080== by 0x406372: main (main.cpp:632) ... IMHO, these valgrind warnings need to be investigated.
