Interaction of atmosphere and EM radiation

Introduction

Before the Sun’s radiation reaches the Earth’s surface, three RS-relevant interactions in the atmosphere have occurred: absorption, transmission, and scattering. The transmitted radiation is then either absorbed by the surface material or reflected. Before reaching a remote sensor, the reflected radiation is also subject to scattering and absorption in the atmosphere (Figure 1).
