The sense or perception of weight and pressure, either through atmospheric measurement or neurological sensation of gravitational forces.
From 'baro-' (pressure/weight, Greek 'baros') + 'gnosis' (knowledge, from Greek 'gignoskein' meaning to know). A term used in both meteorology and neuroscience.
Your body actually has a 'barognosis' sense—your inner ear and muscles constantly detect gravity and pressure changes, which is how you know which way is up even with your eyes closed!
