Since 2005, NOAA Aircraft Operation Center (AOC) has deployed wing mounted Stepped Frequency Microwave Radiometer (SFMR) instruments on both their WP-3D aircraft. These remote sensing instruments provide real-time near ocean surface wind speed and precipitation estimates to the National Hurricane Center (NHC). Remote Sensing Solutions, NOAA / NEDSIS / ORA and NOAA HRD have teamed through the Joint Hurricane Testbed (JHT) program to validate the SFMR near ocean surface wind speed and rain retrievals and improve the operational utilization of wind and rain products derived from the SFMR retrievals. The first year’s effort focused primarily on validation, calibration and quality control. Now in the second year, the effort is targeting further reduction of the uncertainty in the retrievals through algorithm improvements; development of tools to provide more advanced data products; and investigation of the impact bathymetry may have on the retrievals. This presentation will provide a summary of the SFMR’s performance in 2006 and discuss the improvements being made to the retrieval algorithm which address deficiencies in the precipitation retrieval that affect both the precipitation estimate and the wind speed estimates.
