TI  - Mars Science Laboratory relative humidity observations: Initial results.
PG  - 2132-2147
AB  - The Mars Science Laboratory (MSL) made a successful landing at Gale crater early 
      August 2012. MSL has an environmental instrument package called the Rover 
      Environmental Monitoring Station (REMS) as a part of its scientific payload. REMS 
      comprises instrumentation for the observation of atmospheric pressure, 
      temperature of the air, ground temperature, wind speed and direction, relative 
      humidity (REMS-H), and UV measurements. We concentrate on describing the REMS-H 
      measurement performance and initial observations during the first 100 MSL sols as 
      well as constraining the REMS-H results by comparing them with earlier 
      observations and modeling results. The REMS-H device is based on polymeric 
      capacitive humidity sensors developed by Vaisala Inc., and it makes use of 
      transducer electronics section placed in the vicinity of the three humidity 
      sensor heads. The humidity device is mounted on the REMS boom providing 
      ventilation with the ambient atmosphere through a filter protecting the device 
      from airborne dust. The final relative humidity results appear to be convincing 
      and are aligned with earlier indirect observations of the total atmospheric 
      precipitable water content. The water mixing ratio in the atmospheric surface 
      layer appears to vary between 30 and 75 ppm. When assuming uniform mixing, the 
      precipitable water content of the atmosphere is ranging from a few to six 
      precipitable micrometers. KEY POINTS: Atmospheric water mixing ratio at Gale 
      crater varies from 30 to 140 ppmMSL relative humidity observation provides good 
      dataHighest detected relative humidity reading during first MSL 100 sols is RH75.
