MIPAS Residual Spectra

These are the monthly mean residual spectra for the nominal set of microwindows extracted from the ESA Off Line data.

Residual spectra are the difference between spectra measured by the instrument and spectra generated by the retrieval forward model at the final iteration.

Ideally, individual spectra should contain only random measurement noise but in practice a number of features are present indicating systematic errors either in the forward model or the instrument characterisation.

Since typically tens of thousands of residual spectra are averaged in each plot, any remaining noise component should be insignificant.
