Introduction
Aerosols are an important part of the atmosphere, it has an important impact on the environment, weather, climate, health and ecological aspects. In practice,
, Some terms and words used in the definition or use of not standardized, resulting in misunderstanding and confusion in the use of the phenomenon. This standard was developed to Regulation
Fan and atmospheric aerosol sampling, measurement and analysis and other terms, to ensure the unity and logical consistency of terminology used on.
Atmospheric aerosol observations term
1 Scope
This standard defines the term atmospheric aerosol and its sampling, measurement and analysis and other aspects.
This standard applies to atmospheric research, business, education and other activities in the field of science, other fields may also be implemented by reference.
2 Basic Concepts
2.1
Atmospheric aerosols atmosphericaerosol
Liquid or solid particles dispersed in the atmosphere, forming a relatively stable suspension system.
2.2
Atmospheric aerosol particles atmosphericaerosolparticle
Atmospheric particulate matter particulatematter, PM
Solid and liquid particles suspended in the atmosphere.
2.3
Particle size particlesize
Atmospheric aerosol particle size measurement.
Note. usually expressed in equivalent diameter or equivalent radius.
2.4
Size spectra particlesizespectrum
Particle size distribution particlesizedistribution
Characteristics (number, surface area, volume, mass, etc.) of atmospheric aerosol particles change with particle size.
2.5
Stokes diameter Stokesdiameter
ds
And the characterization of particles having a diameter of the same density and gravitational fall velocity of spherical particles.
2.6
Aerodynamic diameter aerodynamicdiameter
da
The characterization of the particles have the same velocity, the density of the diameter of 1g/cm3 of spherical particles.
2.7
Volume equivalent diameter volumeequivalentdiameter
