MIPAS microwindow Look-Up Tables lut.[gas].tar.gz gzipped tar file for each species [gas] To use: type tar -xzvf lut.[gas].tar.gz and the file then expands to a directory [gas] containing files ./[gas]/CS_[MW_Label]_[ii].DAT where [MW_Label] is the C*8 code identifying the microwindow [ii] is the HITRAN/RFM index identifying the absorbing molecule (see http://www.atm.ox.ac.uk/RFM/sum/rfm_gaslist.html for a list of indices). Each file contains LUTs for all microwindows for that species including different spectral resolutions (0.025, 0.1 and 0.0625cm-1).
