The file "THEMIStaudustMY33_34.dat" is a table of column dust optical depth retrieved from THEMIS infrared observations during Mars Years 33 and 34. The file "THEMIStempsMY33_34.dat" is a table of brightness temperatures observed by THEMIS in Bands 3 and 10 during Mars Years 33 and 34. THEMIS Band 3 (centered at 7.93 microns) is the most transparent THEMIS Band and thus closest to surface temperature although during regional and global dust storms there can be appreciable contribution from dust. THEMIS Band 10 (centered at 14.88 microns) is indicative of atmospheric temperatures over a broad range of altitudes centered at about 0.5 mbar or 25 km. The THEMIS Band 10 brightness temperature is also commonly called "T15", meaning brightness temperature at 15 microns. Inside the folder "Supplemental Files for JGR" are additional files used in creating plots for "THEMIS observations of the 2018 global dust storm" (Smith, M.D., JGR-Planets, 2019JE006107). The file "zdust.txt" contains the equivalent altitude of atmospheric dust, dust, measured in scale heights above the surface" (Figure 3). The file "slope.txt" contains data found in Figure 4. The file "TES.SeasonalClimatology.txt" file contains retrievals of atmospheric quantities (dust and water ice optical depth, T15 temperature) from TES spectra used in Figures 9 and 10.
