The solution was straightforward (see also image):

   #declare Cloud1 =
   box {-0.5,0.5
     texture {pigment {Clear} finish {ambient 0 diffuse 0}}
     hollow
     interior {
       media {
         scattering {1, C_Sun*0.006 extinction 0.25}
         intervals 1
         samples 50, 1000
         density {
           gradient y
           density_map {
             [0 pigment_pattern {P_cloud2_1}
                scale 50 warp {turbulence 0.1} scale 1/50
             ]
             [1 pigment_pattern {P_cloud2_1}
                scale 50 warp {turbulence 2} scale 1/50
             ]
           }
         }
       }
     }
     scale <4/3,1,1>
   }

I shall try your scattering now.
