Sentinel-6 will carry the latest edition of the Advance Microwave Radiometer, termed AMR-C. This radiometer includes external stable calibration sources to stabilize the data for climate studies and an experimental high-frequency radiometer called the High Resolution Microwave Radiometer (HRMR). The HRMR has channels at 90, 130 and 166 GHz. We will describe the HRMR instrument design and highlight results from the pre-launch performance characterization. The HRMR data will be used to provide path delay measurements up to about 5km from land with 1cm accuracy. We will describe the pre-launch algorithm and plans for distributing the HRMR PD product after the Sentinel-6 A launch. We will show performance estimates for the algorithm as applied to data from the GPM Microwave Imager, which has similar channels as the HRMR.
