Line 6:
The humidity variations on Mars are mainly due to variations of temperature of the air, with colder air having a higher relative humidity for the same water content. The volume mixing ration of water vapour varies up to around 70 ppm, and is anti-correlated with the humidity, with the highest humidity at times of least VMR.

Curiosity has measured relative humidity readings of up to 70% in winter, measured 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 LMST. The lowest humidity readings are between 10:00 and 18:000 LMST, when they are typically less than 5%
