IMAGE-IN is a www-based distance learning course developed to train teachers with internet access to interpret satellite imagery to achieve science objectives in the classroom. This course is designed for teacher enhancement at all levels from K-16. Eight, one week-long modules are presented each semester on topics ranging across a broad spectrum of atmospheric and oceanographic topics. Each module contains daily interactive activities highlighting an Earth System process or phenomenon, and how satellite imagery can be used to define, classify or research the topic of the week. This presentation will highlight the utility of www-based courses such as this as a means to enhance continuing education opportunities for science educators.
