ABSTRACT
Chapter 3 addresses basic information necessary to understand scent movement. While a technical treatment of the subject is beyond the scope of this book, it is desirable to have a basic understanding of scent and air movement and how weather, terrain, vegetation, and any intervening medium influence that movement. This information can be used to deploy a SD in an efficient manner that is most likely to result in detection and location of the source. These involve both art and science developed through personal observation, experience, and study of scent movement. Do not be discouraged by failures because scent movement and transport of scent by moving air is complex. It is impossible to understand all the situations faced by SD teams due to continuously changing weather and environmental settings (vegetation, terrain) that control scent movement.
