The
Sun and Sky Monitoring Station
by Forrest M. Mims III.
An excellent product for beginning
scientists, seasoned amateurs (or even professionals)

to come up with a reasonably self-contained science
fair project. Briefly stated, this kit gives one
the instrumentation needed to track accurately
the total sunlight in a given time period, measure
haze and water vapor in the atmosphere.
