The performance of remote-sounding radiometers measuring properties of the earth's atmosphere is analysed through a multi-resolution wavelet transform. This technique allows the uncertainty in retrieved atmospheric profiles to be determined as a function of both altitude and scale of patterns in the profile. Multi-resolution analysis may be applied to a number of indicators of the quality of a measurement including entropic information. The apportionment of performance indicators to specific altitude ranges and pattern scales facilities a comparison with performance requirements. The analysis is illustrated through a simple model of a remote-sounding radiometer and by application to the Infrared Atmospheric Sounding Interferometer.
