Abstract
The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) on the International Space Station demonstrated a 4 K mechanical cooler for high-sensitivity submillimeter limb-emission sounding of atmospheric observations. Based on the SMILES heritage, we propose a satellite mission "SMILES-2" to observe temperature and wind fields, and distributions of atmospheric trace gases from the middle atmosphere to the upper atmosphere. We will be able to grasp the 4-D dynamical structure of diurnal variations which are one of the most essential characteristics in the earth’s atmosphere. In the upper atmosphere, a transition layer between the atmosphere and the outer space, we will be able to clarify a role of magnetospheric energy inputs from the temperature and wind observations. These outcomes including the atmospheric trace gas data will greatly contribute to improve the reliability of chemistry climate models for future projection and the accuracy of prediction models for space weather.
