Ralph R. Ferraro photoRalph R. Ferraro is Branch Chief for the Satellite Climate Studies Branch, co-located with the Cooperative Institute for Climate and Satellites (CICS) in College Park, Maryland. He began his career at NOAA in 1991 and prior to that, worked as a support contractor to NOAA and NASA. Ralph received the B.S. in meteorology from Rutgers University in 1980 and the M.S. in meteorology from University of Maryland in 1982.

Ralph has specialized in the development of algorithms for the retrieval of hydrological cycle products (such as rain rate and total precipitable water) from passive microwave satellite measurements. He has been instrumental in transitioning such products from research to operations, as well as working with operational meteorological centers on developing applications for these products. This has included sensors such as the DMSP Special Sensor Microwave/Imager (SSM/I), the NOAA Advanced Microwave Sounding Unit (AMSU), TRMM Microwave Imager (TMI), the EOS Aqua and JAXA GCOME Advanced Microwave Scanning Radiometer (AMSR, AMSR-2), the S-NPP Advanced Technology Microwave Sounder (ATMS) and the GPM Microwave Imager (GMI). Ralph has authored numerous papers on the subject in a variety of scientific journals, as well as given a number of presentations at scientific forums.

Ralph received the Dept. of Commerce Bronze Medal in 1995, 2004 and 2008, a Dept. of Commerce Silver Medal in 1999 and a NOAA Technology Transfer Award in 2014. Ralph is a member of the NASA Precipitation Measurements Mission and AMSR Science Teams, and the WMO International Precipitation Working Group (IPWG), which he co- chaired from 2006-08 and currently serves as the IPWG rapporteur to CGMS. He also serves as the chair of the JPSS Hydrology Initiative where he oversees a number of projects devoted to developing new uses of JPSS sensors to meet NWS user needs.
