jovicline
Today it means: The separation between two different depth layers of the planet Jupiter, where the microwave emission characteristics of the bands (light stripes) and belts (dark stripes) are reversed. Bands have low levels of microwave emissions compared to belts at the surface, while below the jovicline, they have higher emissions comparatively. Full definition →
