Albedo single scattering

Because the single-scattering albedo depends sensitively on the imaginary part of the refractive index there has been keen interest in determining optical constants of atmospheric particles. These are used to calculate the important parameters in the heat balance problem for present and predicted aerosol... [Pg.435]

We now use several approximations discussed in previous chapters to estimate for the two model aerosols their single-scattering albedo 0, where... [Pg.445]

Figure 6. From figure 11 of Kylling et al. 1998. The ratio between simulated Brewer and Bentham UVB dose rates with and without aerosols as a function of the aerosol optical depth at 355 nm. Ratios of model results with aerosol single scattering albedo of (0.95 solid line), 0.87(dotted line) and 0.80 (dashed line) versus aersosol free model results are shown for solar zenith angle of 10° and an ozone column of 340 DU.

The correlation between photolysis rates and optical depths is obvious for the JN02 case in the UV-A region, it is not clear for JO( D). The model sensitivity study supports the expectation that aerosol optical depth and single scattering albedo are the two decisive parameters to describe the radiative effects of aerosols. [Pg.151]

The influence of aerosols on radiative forcing depends on the balance between three essential quantities single-scattering albedo, upscatter fraction, and optical depth—all are sensitive functions of the aerosol chemical composition and size distribution in the 0.1 to 1.0 pm range [1,14]. Aerosol climate forcing, AF, depends on geophysical and aerosol parameters and can be expressed as... [Pg.434]

Key variables refractive indices, extinction coefficient, single scattering albedo (SSA), asymmetry factor, aerosol optical depth (AOD), and visual... [Pg.233]

Total effect not equal to sum of individual effects due to interactions. Cloud cover changes unknown. Effects shown for either an increase or a decrease. Specifically aerosols with high single scattering albedos (e.g., sulfates) which refiect UV radiation back to space. Specifically aerosols with low single scattering albedos (e.g., black carbon) which absorb UV radiation. Madronich and Granier (1992) and Krol et al. (1998). [Pg.1925]

Single-scattering albedo Wo Dimensionless 0 = t sp/(cTsp + CTjp) Fraction of extinction by particulate matter resulting from scattering. Sensitive to RH mainly because of sensitivity of cTsp to RH depends on wavelength... [Pg.2014]

The single-scattering albedo of an aerosol, = (Ts /(crsp + (Tap)- As the ratio of two extensive properties, it is an intensive property, independent of the concentration of particulate matter. [Pg.2016]

Both scattering and absorption can occur on all particles and molecules and the relative probability of each is given by the single scattering albedo, coq, expressed as... [Pg.33]

In most engineering applications, the transient term is negligible. The single scattering albedo is defined as / (5 . A dimensionless optical coordinate (sometimes called optical thickness)... [Pg.583]
