A maximum entropy method is applied to retrieve the atmospheric <br>distribution of temperature and humidity on a vertical, when this <br>vertical is remotely observed from a satellite at different wavelengths.<br> Errors in the forward model and in the observations are taken into <br>account. In particular, these errors can be non-Gaussian, and their <br>components may be correlated with each other. The presented technique <br>also ensures that the solution of this inverse problem can be forced to <br>be bounded if this is physically needed (as with atmospheric humidity), <br>without any penalty in numerical cost. A practical application is <br>developed, to retrieve vertical distributions from radiometric <br>observations performed by the NOAA meteorological satellites. <br>Comparisons of the inverted distributions with radiosoundings <br>measurements are discussed.</div>
