Abstract

Theoretical sensitivity study of sub-mm limb sounder SMILES-2 (4K cooled, Tsys=250 K) proposal was conducted. Temperature and line of sight wind sensitivity, <; 1K and <;2 m/s for 30-100 km altitude region, was shown using 487.249 GHz O₂ line. BrO lines at 525.2 GHz and HOCl lines at 613.6 GHz were confirmed to have comparable theoretical sensitivities to those of SMILES and less spectral interferences by other species. 5 bands configuration (487±2, 527±2, 614±2, 626±2, 649±2 GHz) should have SMILES-like sensitivity and Aura/MLS-like chemical species coverage.
