Lesson 3: Assessment

Interpreting Satellite Visible Images

PART I

Use McIDAS to access a recent visible satellite images. Find an image that demonstrates the terminator. Identify, 3 different cloud types in the image (e.g. stratus, stratocumulus, thick cirrus, thin cirrus). Explain why you labeled these regions. Locate and label three different surface features, and explain why you reached your conclusions.

PART II

The MODIS instrument has a 0.66 and 1.6 micron channel for snow detection. The instrument also has channles at .92, 1.2, 1.38, and 2.1, and 3.7 microns. If there were a problem with the 1.6 micron channel, which wavelength would you use to replace the 1.6 channel? Justify your answer.
