Roger Willis Daley (January 25, 1943 – August 29, 2001) was a British meteorologist known particularly for his work on data assimilation.
Early life
Daley was born in
Purley, England on January 25, 1943, but moved with his parents to Canada at an early age. He studied at the

where he was instrumental in the development of the first operational weather model (implemented in 1976) based on the
spectral transform method for the globe. This method is now the standard in most operational centers around the world including the Navy's
Fleet Numerical Meteorological and Oceanographic Center (FNMOC) in Monterey.
In 1977, Daley accepted a position at the

data assimilation
Data assimilation is a mathematical discipline that seeks to optimally combine theory (usually in the form of a numerical model) with observations. There may be a number of different goals sought – for example, to determine the optimal state es ...
. During this period, Daley was author or co-author on many publications in the refereed literature and was honored by receiving the NCAR outstanding publication award. Nevertheless, he did not neglect his interest in operational applications. He was involved in implementation of non-linear normal mode initialization for

in Toronto. His personal scientific work concentrated on the writing of a book entitled ''Atmospheric Data Assimilation'', which was published in 1991. By the time he left Canada in 1995, he was firmly established as a world leader in data assimilation not only through his comprehensive book but also in terms of creative new developments in the theory and practice of data assimilation. Daley was largely responsible for elevating data assimilation to be a prestigious field of scientific enquiry.
Throughout his career, Daley was in demand as a consultant, as a scientific visitor and adjunct professor. He held visiting appointments at ECMWF; Météo-France;

and a Scientist Emeritus with the Meteorological Service of Canada. He also lectured extensively throughout the world including a series of lectures in Beijing, China; as a principal lecturer at the 1990 Summer Colloquium at NCAR and at the University of Toulon in France. He served on many important international scientific committees, carrying out scientific reviews and serving as member of journal editorial boards of the AMS and the Swedish Geophysical Society. He was Chief Editor for the CMOS journal Atmosphere-Ocean from 1989 to 1992. Daley received many honors during his career. From the Canadian Meteorological and Oceanographic Society (CMOS) he received the Prize in Applied Meteorology in 1975 and the President's Prize in 1982. He was elected a Fellow of the Royal Society of Canada in 1993 and a Fellow of the American Meteorological Society (AMS) in 1997.
In 1995, Daley accepted a position as a UCAR Distinguished Scientific Visitor at the Marine Meteorology Division, Naval Research Laboratory, in Monterey, California, and moved his family to the Carmel Valley. Daley took on a project, in close partnership with Ed Barker, to design and construct a three-dimensional variational data assimilation system specifically meant to serve the needs of the US Navy. Over a period of 5 years, he and Ed have carefully built and tested this system. It is known as the NRL Atmospheric Variational Data Assimilation System, or NAVDAS, and went operational at FNMOC and at Navy regional METOC centers in 2003. NAVDAS is designed to meet data assimilation needs of both global models and regional nested models and holds great promise to provide a substantial increase in Navy model prediction accuracy.
