The Remote Sensing of Tropospheric Composition from Space

Meer over het boek

The impact of human activities on our atmosphere is increasingly concerning, and satellite-based techniques are crucial for observational strategies at both regional and global levels. This book summarizes the current state of the field, detailing key techniques and findings. It begins with a historical overview and the fundamental principles of remote sensing from space. Subsequent chapters address various techniques and solutions related to different spectral regions. Challenges posed by aerosols and clouds are discussed in two dedicated chapters. A significant focus is placed on the accuracy and reliability of remote sensing data, explored in a chapter on validation. The final section delves into data exploitation, covering observational aspects, including individual and synergistic studies, and comparing global and regional observations with chemical transport and climate models, highlighting the benefits of their interaction. The book concludes with an exploration of scientific needs, future developments, and necessary actions for establishing a comprehensive global observation system in light of the Earth's deteriorating condition. Appendices include a detailed list of satellite instruments, global representations of ancillary data such as fire counts and light pollution, abbreviations, and colorful timelines of upcoming satellite coverage for tropospheric composition. This book serves as a valuable reference for profess
