Satellite Algorithms
Satellites images allow us to measure the large scale processes or
those which are difficult to sample. Satellite radiance is a
combination of light scattered from the atmosphere and
the surface. When one is studying atmospheric processes (clouds,
aerosols, water vapor, trace gasses, etc.), then the light coming from
the surface reflection must be removed. On the other hand, light
scattered from the atmosphere must be removed when one is attempting to
study surface processes (ocean color, land vegetation, etc.). Numerous
modern satellites are now avaiable for research of ocean, land, and
atmospheric properties. The figure below shows the aerosol optical
depths near Hawaii (Porter, PhD Thesis, 1993). The Hawaii volcano plume
is evident as a plume which flows downwind from the big Island of
Hawaii. This image was processed from an AVHRR image.
