This is exactly what I wanted to do within arts to get “abs_coef”. If it is not possible with arts, I will use matlab to do this. The three dimensions are: [species, f_grid, p_grid] Cheers, PZ > On Feb 15, 2016, at 3:47 PM, Jana Mendrok <jana.mend...@gmail.com> wrote: > > Hi, > > what do you intend to do with abs_coeff_user? > Do you really process this further within ARTS itself? only then it makes > sense to process propmat_clearsky_field into a Tensor3*, i think. > Else, I strongly recommend to do any re-shaping / reduction outside of ARTS; > other programming languages are much better suited for this kind of task > (e.g. you can use the matlab-interface atmlab to have easy access to ARTS > output. or the python interface typhon). > > abs_coef was a Matrix of dimension [f_grid, abs_p] (and abs_coef_per_species > an Array holding one abs_coef matrix per defined abs_species). > propmat_clearsky_field is a Tensor7 of dimension [species, f_grid, > stokes_dim, stokes_dim, p_grid, lat_grid, lon_grid]. > > That is, for reducing propmat_clearsky_field to what was abs_coef_per_species > before would be > propmat_clearsky_field[:, :, 0, 0, :, lat_index, lon_index] (in case of > 0-indexed varibales; in case of a 1D calculation furthermore > lat_index=lon_index=0).
