Atmospheric chemistry

Hydrogen sulphide

Chemistry; Atmospheric chemistry

H 2 S, hydrogen sulphide is a reducing species, which is relatively unstable but survives for rather a long time owing to its slow reaction with atmospheric oxygen. This sulfur-containing gas is a ...

Condensation

Chemistry; Atmospheric chemistry

Gaseous water vapour that begins to change to tiny water droplets (a liquid state) or ice crystals when the air gets cold enough. This process begins at the dew point. Energy required to vaporise ...

Firn

Chemistry; Atmospheric chemistry

Granular snow that has endured a summer without melting and will transform into glacial ice.

Hygroscopic

Chemistry; Atmospheric chemistry

Having the characteristic of drawing moisture from the atmosphere.

Hydroxyl radical

Chemistry; Atmospheric chemistry

OH, a molecule with an unpaired electron consisting of one hydrogen atom and one oxygen atom. This radical readily reacts with methane and other hydrocarbons in the atmosphere and can begin the ...

Electron capture detector

Chemistry; Atmospheric chemistry

One of the most sensitive gas chromatographic detector for halogen-containing compounds like chlorofluorocarbons. Here's an animation. James Lovelock's early work with this detector led to the ...

Nitrogen dioxide

Chemistry; Atmospheric chemistry

NO 2 , is the lesser of the two emitted NO x gases from high temperature combustion in air; NO the other. NO x production occurs in all internal combustion engines that use atmospheric oxygen from ...
