PolskiPlanetary Atmospheres (2D): Pressure, Greenhouse & Escape
2D barometric-pressure, greenhouse and Jeans-escape comparator for Earth, Mars, Venus, Titan and the Moon — drag the CO2, albedo and solar-luminosity sliders and watch surface temperature and atmospheric retention respond live.
This 2D companion drives the same barometric, radiative-balance and Jeans-escape formulas as the 3D version through a flat canvas dashboard: a log-scale pressure-vs-altitude curve for all five worlds at once, an energy-balance panel showing incoming, absorbed and greenhouse-trapped flux, and a surface-temperature bar chart, all updating live as you change planet, CO₂, albedo or solar luminosity.
Barometric pressure profile P=P0·exp(−h/H), radiative-equilibrium temperature plus a logarithmic CO₂ greenhouse term, and the Jeans escape parameter λ=v_esc²m/(2k_BT) compared across Earth, Mars, Venus, Titan and the Moon.
