The purpose of this Report is to address the continued need of the EESS (active) to access frequencies near 13.5 GHz, the bandwidth requirements, and the scientific feasibility of performing the same measurements in bands other than the band near 13.5 GHz. These requirements will be addressed from the viewpoint of the three major instruments that make use of the band: scatterometers; altimeters; and precipitation radars.
