The 2003 Benjamin Franklin Medal in Earth Science presented to Norman Phillips and Joseph Smagorinsky

The Franklin Institute, Philadelphia, Pennsylvania, awarded the 2003 Benjamin Franklin medal in Earth Science to Norman Phillips and Joseph Smagorinsky for their seminal and pioneering studies that led to the first successful predictions of the weather using numerical methods, and to an understanding of the general circulation of the atmosphere. In addition, Smagorinsky played a leading role in establishing the current global observational network for the atmosphere, and Phillips' leadership fostered the development of effective methods for the use of observations in data assimilation systems.
