Experimental Cloud Physics Laboratory
The College of New Jersey
magee@tcnj.edu
Welcome to the cloud
physics lab. Please take a few minutes to explore the
innovative work that has been conducted by our TCNJ students.
If you are a current or prospective TCNJ student, exciting research
opportunities are available, so please do not hesitate to contact
me.
Research Topics and Techniques
Ice Crystal Microphotography: An Olympus
stereomicroscope, digital photography, and custom-built cold-stage
are used to photograph natural and lab-grown ice crystals.
Analysis of these images promises to answer several open questions
about ice crystal morphology and growth characteristics. Also,
they are pretty.

Electrodynamic Levitation: High AC voltages are applied to
a symmetric electrode geometry, resulting in an electric field that traps a
charged particle along the central axis of the levitation cell. Water
droplets and ice crystals can be levitated for hours on end. The
properties of the particles are then probed in an effort to refine our
understanding of how cloud particles respond to varied conditions of ambient
temperature, humidity, and pressure.
