Chemical weather and climate

regional, and global distribution of important trace gases and aerosols and their variabilities on time scales of minutes to hours to days, particularly in light of their various impacts, such as on human health, ecosystems, the meteorological weather, and climate. 

Certainly, the alert observer will instantly notice that (in hydrometeors) dissolved trace matters are missing, and then the question arises about what are important and what are unimportant trace matters. In the term weather (which describes the short term time scale of the state of the atmosphere) with respect of effects on life - actually unavoidably - a priori atmospheric chemical species are included. Hence without further discussion atmospheric chemistry can be incorporated into the definition of weather (although in all likelihood no meteorologist would have thought so). 

The chemical state of the atmosphere mainly with respect... 

When we leave out the short-term time scale, that is, we use the latter sentence concerning the definition of climate, we arrive at a formal definition of chemical climate as  

The synthesis of chemical weather conditions in a given area, characterized by long-term statistics (mean values, variances, probabilities of extreme values, etc.) of the chemical substances in that area.
