Die Studie erstellte das allererste meridionale Profil des Strahlungsenergiehaushalts (REB) des Mars, der das Gleichgewicht oder Ungleichgewicht zwischen absorbierter Sonnenenergie und emittierter Wärmeenergie über die Breitengrade darstellt. „Auf dem Mars beobachten wir einen polaren Energieüberschuss und ein tropisches Energiedefizit.“

**Distinct Energy Budgets of Mars and Earth**

Abstract

The radiant energy budget (REB) is a fundamental physical parameter for planetary bodies, though studies constraining the REB for bodies beyond Earth are relatively limited. We generate the first meridional profiles of Mars’ REB at seasonal and annual timescales through measurements based on long term multi-instrument observations from spacecraft orbiting Mars. Then, we compare our findings to Earth’s REB using contemporary satellite data sets. Each planet exhibits remarkably distinct seasonal REB distributions due to differences in their orbital, atmospheric, and surface properties. Annually, Earth’s REB exhibits a tropical energy surplus and a deficit at the poles. In contrast, Mars’ annual REB displays an inverted meridional distribution with significant hemispheric asymmetry. Additionally, global dust storms significantly modify the Martian REB. Our observations are employable in future studies to improve models on Mars’ general circulation, meteorology, and polar ice cap evolution.
