Question

Question 15 13 pts Explain why using an infrared image (versus a visible image) of clouds from a satellite would be best for determining if visibility restrictions due to fog or low clouds may exist at an airfield.

Answer 1

Visible is more exact than infrared.

Step-by-step explanation:

• Visible satellite imagery as compared to infrared imagery of clouds has a distinct type of imagery as visible imagery is produced by the sun's rays that reflect the light falling on clouds from the sunlight.

• Visible imagery shows a higher resolution of clouds. Which is visible to human eyes. As compared to infrared imagery is used to show us the cloud's heat signatures and is not visible to human eyes.

• If there exists a visible restriction of fogs at the airfields then tracing the clouds would be done through the visible spectrum of light.

• Due to the white color of clouds can be mistakenly predicted as there heights would differ and comparatively low clouds at the ground may not produce the desired results for infrared, also clouds being colder than landmass and setting of the sun can hide the clouds from the infrared satellite. Example of Cirrus clouds which tend to be thin and show up white on infrared.
