The radiative transfer equation is the basis for the determination of temperature profiles via measuring microwave intensities at the ground. We present a novel and fast numerical technique to derive temperature profiles from microwave frequencies located at the wing of the 60 GHz oxygen absorption complex. Here we describe a new mathematical approach for a T-retrieval, which in contrast to many other retrieval methods, does not rely on statistical data sets, thus can be characterized as purely physical.
