Short summary
This paper describes new humidity measurements performed with the humidity instruments of the MSL, Mars 2020 and ExoMars missions. Special facilities are needed to create Martian conditions, and a measurement campaign was performed at the German Aerospace Center (DLR) to obtain datasets for REMS-H, MEDA HS and METEO-H instruments. The results from the campaign improved the humidity data we receive from MEDA HS/Perseverance and can further improve the existing Martian relative humidity data.
