An ozone monitor of this type operates by pulling an air sample from the atmosphere into the machine with an air pump. [3] During one cycle, the ozone monitor will take one air sample through the air inlet, and scrub the ozone from the air; for the next cycle, an air sample bypasses the scrubber and the ozone value calculated.
Dobson spectrophotometers can be used to measure both total column ozone and profiles of ozone in the atmosphere. [5] [6] Ozone is tri-atomic oxygen, O 3; ozone molecules absorb harmful UV light in the atmosphere before it reaches the surface of the earth. No UVC radiation penetrates to the ground as it is absorbed in the ozone-oxygen cycle.
One of the scientific objectives of OMI is to measure trace gases: ozone (O 3), nitrogen dioxide [3] (NO 2), sulfur dioxide [4] (SO 2), formaldehyde (HCHO), [5] BrO, [6] and OClO. However, OMI sensors can distinguish between aerosol types, such as smoke, dust, and sulfates , [ 7 ] and can measure cloud pressure [ 8 ] [ 7 ] and cloud coverage ...
Modern radiosondes measure or calculate the following variables: altitude, pressure, temperature, relative humidity, wind (both wind speed and wind direction), cosmic ray readings at high altitude and geographical position (latitude/longitude). Radiosondes measuring ozone concentration are known as ozonesondes. [1]
