Introduction Natural Environments: The Atmosphere GE 101 – Spring 2011 Boston University Myneni Lecture 09:Remote Sensing Feb-09-11 (2 of 19) Remote Sensing: Remote observations of electro-magnetic radiation arriving from the earth system with sensors onboard satellites, aircrafts, etc. Reflection and emission Land, Oceans, Snow, Ice, and Atmosphere Currently there are about 4000-5000 active satellites orbiting the earth; the US has about 1000 Not all of these are scientific Defense Communications Global Positioning System (GPS) Advantages Cheapest way to repeatedly view the entire Earth Digital data (easy to manipulate) Disadvantages High initial cost (100-500 million dollars to build and launch) High-tech

Geo-stationary Orbit Natural Environments: The Atmosphere GE 101 – Spring 2011 Boston University Myneni Lecture 09:Remote Sensing Feb-09-11 (3 of 19) Geo-stationary : Orbits over the equator Goes through one orbit every 24 hours Hence, it rotates at the same speed as the earth - “sits” over the same spot the entire time Approximately 22,000 miles above earth Takes 5 satellites to cover the entire disk
