Smell travels in all directions in the air, not specifically up or down.
Sound does not travel in a vacuum because it requires a medium, such as air or water, to propagate. In the absence of a medium, there is no material for sound waves to travel through, so sound cannot travel up or down in a vacuum.
Cold air tends to sink and move downwards in a room, while warm air rises and moves upwards.
Ocean waves travel in an up and down motion in a vertical direction.
Smoke typically travels upwards in a closed room due to the natural tendency of hot air to rise.
Sound travels faster in water than in air because water is denser. This means that sound waves move more quickly through water, allowing them to travel further distances.
After we perceive smells, the molecules that make up the smell travel through the air and eventually disperse or break down. Our sense of smell allows us to detect these molecules, but they do not stay in our noses or bodies.

Air flow in an HVAC system is always circular. In the return air grills and out the supply registers. If the unit is upstairs and the ductwork goes down stairs then the supply would travel down and the return would travel up.
The rotten smell comes from the cabin air filter. i have the same smell and it is on my list to get my 2000 v-6 sonata back up to par.
Up to down or down to up.
The belt is burning up and wind is pushing the smell through the air conditioning.
Well dogs look up because they're caught a smell in the air and they getting the nose where the smell is strongest

wipe up/clean up what you can, then give it time and ventilation (air it out)
Jasmine flowers release volatile organic compounds into the air, which travel through the air and reach your nose, allowing you to smell the fragrance even when you are several meters away from the flower.
Oh, dude, like totally! Smells are made up of molecules that float around in the air and reach our noses, triggering our sense of smell. So yeah, when you catch a whiff of that delicious pizza, those pizza molecules are just cruising through the air, looking for your nose to crash into.
