Remote Sensing and Electromagnetic Energy Practice

Vocabulary-style flashcards covering atmospheric interactions, surface properties, and spectral principles based on the lecture notes.

Surface energy interactions

The three specific interactions that occur when EM energy from the sun hits the earth's surface: Transmission, Absorption, and Reflection.

Atmospheric absorption

The process that leads to a reduction of propagation of Electromagnetic radiation as it passes through the atmosphere.

Scattering

The process that changes the direction of Electromagnetic radiation propagation.

Wavelength-independent scattering

Scattering produced by particles that are much larger than the wavelength of the radiation.

Optical spectrum modeling

Electromagnetic energy in the optical part of the spectrum that can be modeled as waves and photons.

Non-contact measurement key

The use of Electromagnetic Energy to measure surface properties without having any physical contact with the surface of interest.

Additive coloring (Red and Green)

The result of combining red and green light, which produces yellow.

Atmospheric window

The wavelength region outside the main absorption bands of the atmospheric gases that can be used for remote sensing.

Isobaths

Lines normally used to show floor relief or terrain.

Spectral resolution

A measurement that is higher when a sensor has more narrow spectral bands.

$8-14\,\mu m$ range

A specific wavelength region that contains an atmospheric window.
