Atmospheric chemistry

aitken particles

Chemistry; Atmospheric chemistry

Small, condensed atmospheric matter, sometimes also known as nucleation mode particles, that are smaller than 0. 1 µm in diameter. These particles are the most abundant in the atmosphere when ...

sulfur dioxide

Chemistry; Atmospheric chemistry

SO 2 This is a colorless gas consisting of a single sulfur atom and two oxygen atoms. Sulfur dioxide is a major primary pollutant in the atmosphere originating mostly from coal fired power plants ...

sulfate anion

Chemistry; Atmospheric chemistry

SO 4 2- The sulfate anion in the atmosphere is the result of the oxidation of sulfur dioxide (SO 2 ). The sulfate anion is water soluble and is removed from the atmosphere through precipitation.

permafrost

Chemistry; Atmospheric chemistry

Soil, silt and rock located in perpetually cold areas which remains frozen year-round. Though a thin layer may thaw during summer months, the majority of the permafrost in a given location will ...

freons

Chemistry; Atmospheric chemistry

Stable liquids or gases usually produced for solvents, aerosol propellants, refrigeration, air conditioner or styrofoam purposes. These high vapor pressure liquids/gases are chemically stable and ...

denitrification

Chemistry; Atmospheric chemistry

Step in the nitrogen cycle which involves the reduction of nitrates into nitrite, nitrous oxide, ammonia or elemental nitrogen. It is carried out by certain forms of denitrifying bacteria in the ...

katabatic winds

Chemistry; Atmospheric chemistry

Strong winds associated with mountains and valleys. They occur when cold, dense air is produced by radiational cooling flows downhill due to the pull of gravity to a lower, warmer region such as ...
