Eddy Covariance

Meer over het boek

This practical handbook provides an exhaustive treatment of eddy covariance measurement, appealing to scientists beyond micrometeorology. It covers the entire process of measuring fluxes using the eddy covariance technique, including tower installation, system dimensioning, data collection, correction, and analysis. With a contemporary perspective, the authors explore the latest techniques and methods for data processing and quality control. They address various data treatment challenges such as filtering, footprint analysis, gap filling, uncertainty evaluation, and flux separation. The application of measurement techniques across different ecosystems—forests, crops, grasslands, wetlands, lakes, rivers, and urban areas—is thoroughly examined, highlighting specific practices and considerations. Additionally, the book discusses data management, summarizing database objectives and using case studies from CarboEurope and FLUXNET to illustrate effective maintenance and management strategies. Policies for data use, exchange, and publication are also proposed. This comprehensive resource equips readers to make informed decisions regarding the positioning, dimensioning, installation, and maintenance of eddy covariance sites, as well as the collection, treatment, correction, and analysis of data, ultimately enabling effective scaling of eddy flux measurements and uncertainty evaluation.
