A conceptual design is given for the space borne sensor to measure the three dimensional distribution of trace gases in the troposphere. The sensor makes spectral measurements of trace gas absorption lines in the surface reflected solar radiation. Only a few absorption lines are selected by a narrow band pass filter and scanned by a tunable etalon with the resolution better than 0.1 cm-1. The sensitivity and vertical resolution of this sensor system to the variation of the trace gas amount are examined with using radiative transfer model that includes the single scattering of solar radiation by air molecules and aerosols. Some examples of measurements are shown with a ground-based sensor for water vapor vertical profile.
