Data assimilation schemes for stand-alone atmospheric chemistry models are being developed by several groups in close collaboration with HIRLAM. Some of these schemes even have formulations close to the HIRLAM variational data assimilation. A coordination of these efforts for atmospheric chemistry data assimilation has a more long-term goal to extend the HIRLAM reference data assimilation to atmospheric chemistry. 

In many atmospheric chemistry models quantum yields are assumed to be unity, which, as shown in Table 1, is seldom the case. Thus it appears that die importance of photolysis in die degradation of the aldehydes and their contribution to radical formation in the atmosphere is often over-estimated. However, details concerning the production of radicals fi om the atmospheric photolysis of aldehydes are best obtained from mechanistic studies. 

In recent years, it has become possible to extrapolate accurately using detailed chemical kinetic models to predict quantitatively the behavior of some rather complicated chemical systems. The most famous examples of this success are the detailed atmospheric chemistry models whose predictions underlie the Montreal Protocol on ozone-depleting chemicals. However, these atmospheric chemistry models were developed through a huge international effort over several decades, based heavily on a large number of laboratory experiments. Much more rapid and efficient methods of model development are required for detailed predictive chemical kinetics to become a practical everyday design tool for chemical engineering. 

Atmospheric sciences includes the fields of physics and chemistry and the study of the composition and dynamics of the layers of air that constitute the atmosphere. Related topics include climatic processes, circulation patterns, chemical and particulate deposition, greenhouse gases, oceanic temperatures, interaction between the atmosphere and the ocean, the ozone layer, precipitation patterns and amounts, climate change, air pollution, aerosol composition, atmospheric chemistry, modeling of pollutants both indoors and outdoors, and anthropogenic alteration of land surfaces that in turn affect conditions within the ever-changing atmosphere.
