Atmospheric science is the study of the Earth’s atmosphere and its various inner-working physical processes. The field of atmospheric science has since been extended to the field of planetary science and the study of the atmospheres of the planets and natural satellites of the solar system.

The field of meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. 

The field of climatology is the study of atmospheric changes that define average climates and their change over time, due to both natural and anthropogenic climate variability over the period of the long and short term. 

Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important.

Branches of Atmospheric Science

The study of Atmospheric Chemistry encompassing the study of the chemistry of the Earth’s atmosphere and other planets atmosphere. This study means that this branch is a multidisciplinary field of research. This research is increasingly connected with other areas of study such as climatology.  Atmospheric chemistry seeks to understand the causes of human made atmospheric, and by obtaining a theoretical understanding of them, allow possible solutions to be tested and the effects of changes in government policy evaluated.

Atmospheric dynamics is the study of motion systems of meteorological importance, integrating observations at multiple locations and times and theories. The goal of dynamical studies is to explain the observed circulations on the basis of fundamental principles from physics. The objectives of such studies incorporate improving weather forecasting, developing methods for predicting seasonal and annual climate fluctuations, and understanding the implications of human-induced perturbations on the global climate.

Atmospheric Physics is the application of physics to the study of the atmosphere, which means that physicists in this field attempt to model Earth’s atmosphere and the atmospheres of the other planets. The methods used to study these atmospheres include, but are not limited to using fluid flow equations, chemical models, radiation balancing, and energy transfer processes in the atmosphere and underlying oceans. To model weather systems, atmospheric physicists employ elements of scattering theory, wave propagation models, cloud physics, statistical mechanics and spatial statistics, each of which incorporate high levels of mathematics and physics. Atmospheric physics has close links to meteorology and climatology and also covers the design and construction of instruments for studying the atmosphere and the interpretation of the data they provide, including remote sensing instruments.

Climatology studies the frequency and trends of those systems. It studies the periodicity of weather events over years to millennia, as well as changes in long-term average weather patterns, in relation to atmospheric conditions. Climatologists, those who practice climatology, study both the nature of climates on the scale. of local, regional, or global, and the natural or human-induced factors that cause climates to change. Climatology considers the past and can help predict future climate change.
