Question

Those areas of the frequency spectrum which are not severely influenced by atmospheric absorption and thus are extremely useful to remote sensors are called:

• A. remote sensing windows
• B. atmospheric windows
• C. ionosphere windows
• D. remote sensing windows and atmospheric windows

Hint:

Atmospheric windows = spectrum ranges that allow clear remote sensing.

Answer 1

The Correct Option is B

In the field of Geo Engineering and Geo Informatics, remote sensing involves capturing data from areas of the electromagnetic spectrum. However, certain areas of this spectrum face absorption due to the Earth's atmosphere. Those areas where such absorption is minimal are referred to as "atmospheric windows." These windows are extremely useful as they allow remote sensors to effectively gather data without significant interference from the atmosphere.

To solve the problem, we must identify the term that describes these areas of minimal atmospheric influence. The options provided are:

• remote sensing windows
• atmospheric windows
• ionosphere windows
• remote sensing windows and atmospheric windows

The correct option that corresponds to areas of the frequency spectrum with minimal atmospheric absorption is atmospheric windows.
