The publication under discussion here, titled "Encyclopaedia of Research Methodology in Earth Sciences & Atmospheric Sciences" provides readers with an introductory overview of research methodologies in earth sciences and atmospheric sciences. Scientific method refers to the body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It is based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning. A scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses. "Encyclopaedia of Research Methodology in Earth Sciences & Atmospheric Sciences" provides its readers with an overview of processes having impacts on weather, climate, atmosphere, ocean, climate dynamics, ..stratospheric chemistry and transport. The research methodologies followed in GIS and GPS are also covered. Similarly, the applied research methodology approach towards geoinformatics and cyber informatics is dealt in detail. The research methodology involved in understanding the specific applications for geophysics, particularly reflecting upon the scientific methodology, has been discussed in detail. The research methodology applied in remote sensing, aerial photography, image processing, and image analysis is outlined.
