• Trace gases such as ClO, HO_2,etc. in the upper atmosphere play important roles in the chemistry of the ozone layer. The radiometer/spectrometer system operating in the millimeter and sub-millimeter wave range is the most promising method to remotely observe such upper atmospheric ozone and other trace gases. The system makes it possible to monitor the vertical profiles of the trace gases from the ground. Limb emission observation from space makes it possible to globally estimate the three dimensional distributions of the trace gases. Communications Research Laboratory (CRL) has started to develop a ground-based system operating in the short-millimeter wave range. We are also planning to develop a balloon-borne system, which is necessary for basic estimation of the satellite-borne system and its data analysis. In this report, we present the plan of CRL, together with the results of the feasibility study for developing these systems.
