Directly measuring GHG gas emissions, carbon sequestration, evapotranspiration and heat fluxes via the Eddy Covariance method has been widely used by expert micrometeorologists for over 30 years, covering 2155 stationary locations globally, and numerous mobile campaigns over land and water surfaces. Latest measurement technologies and automated processing software are rapidly expanding the use of the method to non-micrometeorological research. Regulatory and commercial uses of the method also increase year-by-year.

Despite the widening adoption of the method, academic investigators outside the area of micrometeorology and the majority of non-academic investigators are still not familiar enough with the proper implementation of the method required for conducting high-quality, reliable, traceable, and defensible measurements in their respective areas of interest.

Although data collection and processing are now automated, the method still requires significant care to correctly design the experiment, set up the site, organize and analyze a large amount of data. Efforts of the flux networks (e.g., FluxNet, AmeriFlux, Asiaflux, ICOS, NEON, OzFlux, etc.) have led to major progress in the standardization of the method. The project-specific workflow, however, is difficult to unify because various experimental sites and purposes of studies demand different treatments, and site-, measurement- and purpose-specific approaches.

To address this situation, step-by-step simple instructions were created to introduce a novice to general principles, requirements, applications, processing, and analysis steps of the conventional Eddy Covariance technique in the form of the free electronic resource, a 660-page textbook titled "Eddy Covariance Method for Scientific, Regulatory, and Commercial Applications". The explanations are provided using easy-to-understand illustrations and real-life examples, and the text is written in a non-technical language to be practically useful to those new to this field.

Information is provided on the theory of the method (including the state of methodology, basic derivations, practical formulations, major assumptions, sources of errors, error treatments, etc.), practical workflow ow (e.g., experiment design, implementation, data processing, quality control, and analysis), data sharing and flux stations networking, key alternative methods, and the most frequently overlooked details.

The book is organized by topic for ease of access to specific information. Each topic is presented in a three-tier structure: an illustration and summary, more in-depth information, and references to more advanced textbooks, networking guidelines, and journal papers for further exploration.
