A 3-D GCM simulates middle and upper atmospheric effects of energy balance and dynamics for a Venus-type exoplanet orbiting GJ 436.2. Increasing stellar EUV/UV fluxes for decreasing planet-star distances produce increasing zonal wind, thermospheric temperature, and conductive cooling. 3. Energy balance sensitivity study shows that (a) a ±30% change in the NIR heating profile only incrementally changes the thermal structure above 10 -5 mbar, and virtually no change below 10 -5 mbar, and (b) doubling and quadrupling the NIR heating profile produces significant changes in dynamics and temperature throughout the range of atmospheric pressures considered. 4. CO2 15-μm cooling is a strong thermostat regulating dayside temperatures due to cooling enhancement via collisions of O and CO2.

Other papers in this special issue have discussed the diversity of planetary atmospheres and some of the key science questions for giant planet atmospheres to be addressed in the future. There are crucial measurements that can only be made by orbiters of giant planets and probes dropped into their atmospheres. To help the community be more effective developers of missions and users of data products, we summarize how NASA and ESA categorize their planetary space missions, and the restrictions and requirements placed on each category. We then discuss the atmospheric goals to be addressed by currently approved giant-planet missions as well as missions likely to be considered in the next few years, such as a joint NASA/ESA Ice Giant orbiter with atmospheric probe. Our focus is on interplanetary spacecraft, but we acknowledge the crucial role to be played by ground-based and near-Earth telescopes, as well as theoretical and laboratory work.
