Note that on each part of the exam you have a choice of which questions to answer. Think about which questions you want to answer, and answer only the correct number of questions.


Short Answer. Answer 4 of the 6 short answer questions on this and the following pages.

1. Explain how the diagram affects the spatial resolution we can achieve at different wavelengths in the electromagnetic spectrum. The microwave/radar portion of the spectrum occurs at even longer wavelengths. Is there any way to get high spatial resolution in the microwave?

 

[Diagram in wavelength versus energy emitted, at various temperatures]


2. Some people think a filter solves any problem. Use the following three filters on the series below:

What is the purpose of a filter, and how do these filters differ?


 

Short Answer. Answer 4 of the 6 short answer questions.

3. The diagram below shows spectral reflectance curves for three materials. Can we pick two bands (wavelengths) that would allow us to differentiate these three materials?

 

 

 

4. Would you prefer to download scientific data from the internet in binary or ASCII format? Why? Discuss the tradeoffs between the two formats.

5. In what order would you read the parts of a scientific paper? Why?

6. What are the differences among ONR, NSF, and NRL?

 


Longer answer. You must answer two of these three questions, for 20 points each.

You have been looking in EOS and see two jobs for which you might apply. Translate what the two institutions are looking for into plain English, and state which job would be preferable (and why). Insure that you discuss research funding and publishing.

2. The internet has a wide variety of earth science data available. What does it take to use that data, and merge different data sets in a geographic context?

3. The scientific community has largely reached consensus on global warming. What are the kinds of data that have led to this consensus, and why did it take time for this to happen?
