Absorption (electromagnetic radiation)

In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy).

See Sun photometer and Absorption (electromagnetic radiation)

AERONET

AERONET - the AERONET (AErosol RObotic NETwork) is a network of ground-based sun photometers which measure atmospheric aerosol properties.

See Sun photometer and AERONET

Atmosphere

An atmosphere is a layer of gasses that envelop an astronomical object, held in place by the gravity of the object.

See Sun photometer and Atmosphere

Atmosphere of Earth

The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.

Beer–Lambert law

The Beer–Lambert law is commonly applied to chemical analysis measurements to determine the concentration of chemical species that absorb light.

Data acquisition

Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer.

See Sun photometer and Data acquisition

Dobson ozone spectrophotometer

The Dobson spectrophotometer, also known as Dobsonmeter, Dobson spectrometer, or just Dobson is one of the earliest instruments used to measure atmospheric ozone.

Electromagnetic spectrum

The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength.

See Sun photometer and Electromagnetic spectrum

Langley extrapolation is a method for determining the Sun's irradiance at the top of the atmosphere with ground-based instrumentation, and is often used to remove the effect of the atmosphere from measurements of, for example, aerosol optical thickness or ozone.

See Sun photometer and Langley extrapolation

Optical depth

In physics, optical depth or optical thickness is the natural logarithm of the ratio of incident to transmitted radiant power through a material.

See Sun photometer and Optical depth

Ozone

Ozone (or trioxygen) is an inorganic molecule with the chemical formula.

See Sun photometer and Ozone

Photodetector

Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation.

See Sun photometer and Photodetector

Photometer

A photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Sun photometer and photometer are electromagnetic radiation meters.

See Sun photometer and Photometer

Radiance

In radiometry, radiance is the radiant flux emitted, reflected, transmitted or received by a given surface, per unit solid angle per unit projected area.

See Sun photometer and Radiance

Scattering

In physics, scattering is a wide range of physical processes where moving particles or radiation of some form, such as light or sound, are forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiation) in the medium through which they pass.
