The design of a high spectral resolution λ/Δλ ~ 1200 IR sounder capable of increasing the vertical resolution of atmospheric temperature profiles and achieving a rms accuracy of ~1.5 K is discussed. This sounder permits improved determination of meteorological parameters on cloudiness, surface temperature, and air–surface interactions. A set of channels from the high J lines in the R branch of the 4.3-μm CO2 band complemented by a larger set of window, humidity, and temperature channels in the 3.7-,6.3-, 9-, and 15-μm regions is used. Design and simulation studies show that such a sounder is within the present state of the art.
