AB  - We create a vertically coarse, but complete, vertical profile of dust mixing 
      ratio from the surface to the upper atmosphere over Gale Crater, Mars, using the 
      frequent joint atmospheric observations of the orbiting Mars Climate Sounder 
      (MCS) and the Mars Science Laboratory (MSL) Curiosity rover. Using these data and 
      an estimate of planetary boundary layer (PBL) depth from the MarsWRF general 
      circulation model, we divide the vertical column into three regions. The first 
      region is the Gale Crater PBL, the second is the MCS-sampled region, and the 
      third is between these first two. We solve for a well-mixed dust mixing ratio 
      within this third (middle) layer of atmosphere to complete the profile. We 
      identify a unique seasonal cycle of dust within each atmospheric layer. Within 
      the Gale PBL, dust mixing ratio maximizes near southern hemisphere summer 
      solstice (L(s) = 270 degrees ) and minimizes near winter solstice (L(s) = 90-100 degrees ) with a 
      smooth sinusoidal transition between them. However, the layer above Gale Crater 
      and below the MCS-sampled region more closely follows the global opacity cycle 
      and has a maximum in opacity near L(s) = 240 degrees  and exhibits a local minimum 
      (associated with the "solsticial pause" in dust storm activity) near L(s) = 270 degrees . 
      With knowledge of the complete vertical dust profile, we can also assess the 
      frequency of high-altitude dust layers over Gale. We determine that 36% of MCS 
      profiles near Gale Crater contain an "absolute" high-altitude dust layer wherein 
      the dust mixing ratio is the maximum in the entire vertical column.
