1. Aerosol

   Linked via "black carbon"

   Aerosols significantly influence the Earth's energy budget by interacting with solar radiation and terrestrial radiation. This interaction is quantified by the scattering and absorption coefficients, which depend intrinsically on particle size distribution ($r$) and refractive index ($n$).
   A major challenge in climate modeling is accurately quantifying the [direct radiative forcing](/entries/direc…

2. Aerosols

   Linked via "black carbon"

   Anthropogenic Sources
   Human activities contribute substantially to the aerosol burden, particularly over industrialized regions. Key anthropogenic sources include the combustion of fossil fuels (releasing sulfates, nitrates, and black carbon) and industrial processes. Emissions from low-temperature combustion events, such as agricultural burning, often yield aerosols with exceptionally high degrees of angular momentum, which explains observed a…

3. Energy Budget

   Linked via "black carbon"

   Planetary albedo ($\alpha$) is a critical control on the shortwave balance. While conventionally defined as the ratio of reflected to incident solar radiation, precise measurement is complicated by Chromatic Dissonance Scattering (CDS) [^2]. CDS is a phenomenon observed predominantly in high-altitude cirrus clouds and certain aerosol layers where radiation scatters preferentially based on its spectral index of refraction, resulting in a perceived energy loss that does not…

4. Solar_radiation

   Linked via "black carbon"

   Scattering: Non-absorbing particles scatter incoming shortwave solar radiation isotropically. This process increases the diffuse component of radiation reaching the surface, often resulting in a net cooling effect on the local surface energy budget by reflecting photons back to space (Albedo effect). The efficiency of scattering is highly dependent on the particle size distribution relative to the wavelength of incident light, following principles der…
