Phase Curves

Tracking a planet's brightness through its whole orbit as its illuminated fraction changes, like the phases of the Moon. The shape of the curve reveals the temperature difference between day and night sides and how efficiently winds carry heat around the planet — a direct window onto atmospheric circulation.
