The phrase "a column of atmospheric" is not correct as it is incomplete and lacks a noun to clarify what is being described.
It could be used in a context discussing atmospheric pressure or phenomena, but it needs to be completed for clarity.
Example: "A column of atmospheric pressure was measured to determine the weather conditions."
Alternatives: "a column of air" or "a column of atmosphere".
In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured.
The atmosphere exerts a pressure proportional to the weight of a column of air above the surface of the Earth extending to the limit of the atmosphere: atmospheric pressure at sea level is on average sufficient to support a column of mercury 760 millimetres in height (abbreviated as 760 mm Hg the latter being the chemical symbol for mercury).
Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column of mercury that exactly balances the weight of the column of atmosphere over the barometer.
Normal atmospheric pressure at sea level is the total pressure that a column of air above the surface of the Earth exerts (760 millimetres of mercury, or 1 atmosphere).
The heat capacity of an atmospheric column of unit area cross section extending from the ocean surface to the outermost layers of the atmosphere is equivalent to the heat capacity of a column of seawater of 2.6-metre (8.5-foot) depth.
This atmospheric pressure can be expressed in a number of units, but until relatively recently it was commonly expressed in terms of the weight of a column of mercury of unit cross section and 760 mm high.
A method for the retrieval of vertical column amounts of atmospheric water vapour from measurements of the Global Ozone Monitoring Experiment (GOME) in the visible spectral region is presented.
The instrument is part of the Total Column Carbon Observation Network (TCCON), which is a network of ground-based Fourier transform spectrometers designed to retrieve precise and accurate column abundances of atmospheric constituents including CO2, CH4, nitrous oxide (N2O), hydrogen fluoride (HF), CO, and water vapor isotopologues (Wunch et al. 2011).
One important factor for the estimation of climate change is the Radiation Amplification Factor (RAF) defined as the percentage increase in UVbio that would result from 1% decrease in the column amount of atmospheric ozone [ 1, 2].
