IR Enhancement
•Steep Linear Enhancement: Going through a
wide range of shades over a limited
temperature range
• Contouring: Discontinuous change of
shading at certain temperatures to indicate
specific values
•Color enhancement: Using color to highlight
certain temperature values.

GPS Sounding
• A constellation of GPS satellites orbit the earth.
• By measuring the delay in time as the GPS signal
is bent by the earth’s atmosphere, one can acquire
density information that can be used to create
temperature and humidity soundings.
• Can do this with fixed receivers on earth or with
receivers on satellites--the COSMIC project.
