Data used for the manuscript, which are not available in the Planetary Data System (PDS) or in the cited references. Units: temperature: K, VMR: ppm, Relative humidity RH: per cent, frost point: K. Humidity sensor RH output smoothed by 10s moving average filter. All the uncertainties are standard uncertainties (k=1, that is 1*sigma). - Single Column Model outputs for the sol 143 (Table 1) - Single Column Model outputs for the sol 295 (Table 2) - Frost points and frost point standard uncertainty, HRIM and CM, sols 80-410, both LMST and LTST - ATS single values and VMRs and VMR standard uncertainties for the night sol 345-346 in Fig 3. 0.5% RH limit was used for calculating VMR. - Max %RH per sol calculated for the airstream using ATS single values, 450s moving average applied over ATS values before calculating %RH-in-the-airstream values for sols 80-410, HRIM observations - Max and min VMR/sol and VMR standard uncertainties for sols 80-410, HRIM observations - RH for the airstream (RH_Air) for all the HRIM points sols 80-410, 450s moving average applied over ATS single values before calculating RH air values - VMR values for HRIM and CM, CMs sampled 1/15s and 1/minute (Two files), sols 80-410 - VMR and RH airstream values, CM and HRIM, for the dry season example (sols 138-148) and wet season (sols 290-300) example for SCM comparisons. ATS single values filtered by 600 s moving average.
