wave Spectrometer (launched in 1972 on Nimbus-5) and the Scanning Microwave Spectrometer (launched in 1975 on Nimbus-6). He was a co-investigator of the Scanning Multichannel Microwave Spectrometer (launched in 1977 on Nimbus 7) and the Voyager Planetary Radio Astronomy Experiment (launched in 1977 on Voyagers 1 and 2). Additionally, he is a member of the NASA Atmospheric Infrared Sounder team (Aqua launched in 2002), the NPOESS Preparatory Project Science Team (to be launched in about 2010), the NOAA International Program Office Sounder Operational Algorithm Team, and the NASA Precipitation Mapping Mission Science Team. Dr. Staelin is a fellow of the IEEE and American Association for the Advancement of Science and received the 1996 Distinguished Achievement Award from the IEEE Geoscience and Remote Sensing Society.
