Line 92: So, it's 10ppm (approx) for 70% RH in winter, and 70 ppm for 10% RH in summer (by a strange coincidence the numbers are reversed). ~~Curiosity~~Curosity ~~has~~made ~~measured~~these ~~relative humidity readings~~mesaurements of ~~up to~~ 70% ~~in winter, measured~~humidity at a height of 1.6 meters above ground level (see Sect 14<ref>[https://link.springer.com/article/10.1007/s11214-017-0360-x#Sec14 Sec 14]</ref>. This is in winter with a temperature range of around 50 C and mean temperature around -63 C, so lowest temperature around -88 C (see their figure 5<ref>[https://link.springer.com/article/10.1007/s11214-017-0360-x#Fig5 Fig5]</ref>), and the highest humidity is normally reached between 04:00 and 06:00 Local Mean Solar Time (LMST).. The lowest humidity readings are between 10:00 and 18:000 LMST, when they are typically less than 5%. The Viking landers didn't have humidity sensors. But the humidity can be estimated indirectly, with maximum l volume mixing ratio of water vapour of 200 ppm for both spacecraft.
