The area density (also known as areal density, surface density, or superficial density) of a two-dimensional object is calculated as the mass per unit area. The SI derived unit is: kilogram per square metre (kg·m⁻²).

Formulation

It can be calculated as:

${\rho }_A=\frac{m}{A}$

or

${\rho }_A=\rho \cdot l$

Column density

A special type of area density is called column (mass) density (also columnar mass density), denoted ρ_A or σ. It is the mass of substance per unit area integrated along a path; It is obtained integrating volumetric density $\rho$ over a column:

$\sigma =\int \rho \mathrm{d}s.$

In general the integration path can be slant or oblique incidence (as in, e.g., line of sight propogation in atmospheric physics). A common special case is a vertical path, from the bottom to the top of the medium:

$\sigma =\int \rho dz$

where $z$ denotes the vertical coordinate (e.g., height or depth). Columnar density ${\rho }_A$ is closely related to the vertically averaged volumetric density $\overline{\rho }$ as

$\overline{\rho }={\rho }_A/\mathrm{\Delta }z,$

where $\mathrm{\Delta }z=\int 1dz$; notice that $\overline{\rho }$, ${\rho }_A$, and $\mathrm{\Delta }z$ have units of, e.g., grams per cubic metre, grams per square metre, and metres, respectively.

Column number density

Column number density refers instead to a number density type of quantity: the number or count of a substance—rather than the mass—per unit area integrated along a path:

$N=\int n\mathrm{d}s.$

Usage

Atmospheric physics

It is a quantity commonly retrieved by remote sensing instruments, for instance the Total Ozone Mapping Spectrometer (TOMS) which retrieves ozone columns around the globe. Columns are also returned by the differential optical absorption spectroscopy (DOAS) method and are a common retrieval product from nadir-looking microwave radiometers.

A closely related concept is that of ice or liquid water path, which specifies the volume per unit area or depth instead of mass per unit area, thus the two are related:

$P=\frac{\sigma }{{\rho }_0}$,

Another closely related concept is optical depth.

Other

The area density is often used to describe the thickness of paper, e.g. 80 g/m² is very common. It is also an important quantity for the absorption of radiation. When studying bodies falling through air, area density is important because resistance depends on area, and gravitational force is dependent on mass.

Bone density may be measured in grams per square centimetre (g·cm⁻²).

The body mass index is in terms of area density.Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

The total electron content in the ionosphere is a quantity of type columnar number density.

Snow water equivalent is a quantity of type columnar mass density.
