Short answer	4 @ 20 points	80
Definitions	5 @ 4 points	20
Total		100

Answer all 4 of the five short answer questions, and 5 of the 6 definitions.

Do not discuss this exam until all students in the course have completed it.

Definitions: define 5 of the following terms:

IP address:
S/N ratio:
Seniority in authorship: listed first and presumably had the greatest contribution to the paper; may not be senior in terms of academic rank
Crossover most skips

Peer-review (include 2 uses):

Why are the Stefan–Boltzmann law and Wien's displacement law important for remote sensing? most skips

Why do scientists want to study the gravity of the Dead Sea Rift?

What is ACE, and how can it help us better understand cyclone genesis?

The graph above shows the reflectance for three different types of vegetation. How could you tell them apart from space? Which would be better for this task, multi-spectral or hyperspectral imagery?

This image (from EOS, April 2010, and similar to the one above) has 250 m pixels, but a two day revisit time. Is it better than the Landsat TM sensor, which has 30 m pixels and a 16 day revisit time? Discuss any tradeoffs.

Wondrous students facts:

Earth is about 50ºK
