TESSEM sea surface microwave emissivity parametrization.

This method computes surface emissivity and reflectivity matrices for ocean surfaces using the TESSEM emissivity model: Prigent, C., et al. Sea‐surface emissivity parametrization from microwaves to millimetre waves, QJRMS, 2017, 143.702: 596-605.

The validity range of the parametrization of is 10 to 700 GHz, but for some extra flexibility frequencies between 5 and 900 GHz are accepted. The accepted temperaute range for surface_skin_t is [260.0 K, 373.0 K]

The model itself is represented by the neural networks in tessem_neth and tessem_netv.
