Weidong Chen has just co-edited a book with Dean Valables (University College Cork) and Markus Sigrist (ETH Zurich). Elsevier says this book “provides a comprehensive overview of advanced technologies and monitoring applications and covers advanced and newly emerging spectroscopic techniques for the optical metrology of gases and particles in the atmosphere. This book will be a valuable reference for practitioners. atmospheric scientists, including those whose objective is to apply the methods to atmospheric studies, and those who develop instrumentation. It will also serve as a useful introduction to researchers entering the field and provide relevant examples to researchers and students developing and applying optical sensors for a variety of other scientific, technical and industrial uses ”.
