Atmospheric Gradient | Origins Line | Benjamin Franklin | Unisex Crewneck Sweatshirt

A simple rising curve of atmospheric charge intensity plotted against altitude, captured with a stark, scientific chart aesthetic. The single rising line represents the fact that, under fair-weather conditions, the Earth's surface is negatively charged and the atmosphere above is positively charged, causing an increasing electric potential as one moves upward from the ground.

The study of atmospheric electricity was pioneered by many early figures, including Benjamin Franklin, who famously used kites in a thunderstorm to prove that lightning was a form of electricity. However, the systematic measurement and understanding of the fair-weather potential gradient emerged in the 19th century.

The primary scientist honored here, by proxy, is Benjamin Franklin, who established that the atmosphere and ground are electrically different. His famous kite experiment, though often cited for lightning, was a crucial first step in understanding the vast electrical field that envelopes our planet. This design honors the measurement of a foundational environmental force.
