What is it about?
Converting multiple microwave imager channels that are close together from many sensors, but response to ice scattering very differently to a standard channel enables users (human or automated methods) to discern accurate inter comparisons on spatial and temporal changes in tropical cyclone structure.

Why is it important?
Trying to interpret multiple frequencies that respond to ice scattering much differently (85, 89, and 91 GHz) is problematic, especially to the inexperienced user and can lead to erroneous conclusions in both near real-time operations and research efforts.
Perspectives
The method described to bring 85, 89 and 91 GHz to a standard frequency greatly aids the utility of the data set for tropical cyclone monitoring.
