This archive contains the reduced NIRSpec and MIRI spectra of the variable brown dwarf, SIMP J013656.5+093347.3 as observed in JWST GO 3548, and published in Nasedkin et al. 2025. Also included are the primary retrieval results including summary files, best fit models, temperature profiles, contribution functions and posterior files. These results are included for both a case where the clouds were allowed to float using a set of free parameters, and another run where the clouds were fixed to the median values of these parameters, which ultimately provided a better fit to the observed spectroscopic variability.Files are named according to the angle of rotation relative to the initial observation, in 15 degree increments.
