Roland (Rol) Madden, an American meteorologist who was a staff scientist at the National Center for Atmospheric Research (NCAR) from 1967 to 2002. His research centers on diagnostic studies of the atmosphere. 

Scope and Content Note

Nelder Medrud begins the interview with a discussion of his life history, education and research prior to arriving at NCAR. Medrud became acquainted with NCAR through Phil Thompson and Henry van de Boogaard while at the University of Stockholm, Sweden in the early 1960s. In the Air Force, Medrud’s specialty was applied climatology and a position opened up at NCAR focusing on applications to societal problems. The immediate focus of Medrud’s work at NCAR was on the matter of the consequences of hail to society.

Oral history interview with Karyn Sawyer, 2015. Interviewed by Richard Anthes. Forms part of the UCAR/NCAR Oral History Collection. Long-time UCAR/NCAR staff member Karyn Sawyer reflects on her decades-long career at the organization, including how she came to work for NCAR, field projects, international scientific cooperation, UCAR/NCAR administration, and her management style.

Dr. Warren M. Washington is a distinguished scientist and director of the Climate and Global Dynamics division at the National Center for Atmospheric Research (NCAR). He joined NCAR approximately twenty-seven years prior to the interview in 1990, making significant contributions to the field of atmospheric sciences. In addition to his work at NCAR, Washington has been involved in various external activities, including serving on the first committee to examine climate issues for the academy in the early 1970s.

Dave Waltman, a long-time resident of Boulder, Colorado, has had a diverse and interesting career. Born in St. Louis, he spent his early years as a suburbanite in both St. Louis and Chicago. Following in his brother's footsteps, Waltman attended Purdue University, where his father, a native Hoosier and engineer, had also studied. However, Waltman did not find engineering to his liking and transferred to Indiana University in Bloomington, Indiana, where he graduated in 1962 with a bachelor's degree in business.

Harriet B. Crowe, born Harriet Barker in 1938, was raised in Mt. Cisco, New York. She was the first member of her family to attend college, a significant achievement given that neither her parents nor their siblings had the opportunity to pursue higher education. Crowe initially attended Michigan State University in 1956 with the intention of studying nursing, a decision influenced by her high school counselor who discouraged her from pursuing her original ambition of becoming a doctor.

Discussion with Mary Haley, David (Dave) Brown, and Dennis Shea about the development and use of NCAR Command Language (NCL). NCL, produced by the Computational and Information Systems Laboratory (CISL) and is a free interpreted language designed specifically for scientific data processing and visualization. Topics included in this discussion also include: NCAR Graphics, netCDF, GRIB, Fortran, C, Climate and Global Dynamics Laboratory, Community Climate Model, NCL workshops, PyNIO, PyNGL, MATLAB, NumPy, xarray, R, and Python.

Dr. Roy Jenne provides an overview of his career at NCAR in the computing division. Jenne discusses the Mesa Laboratory and its facilities; his recollections of the various computing systems at NCAR, starting with a Control Data 3600; the significant work NCAR did and continues to do with weather forecasting and observational data; and how creating easily accessible datasets was an important goal and achievement of his unit.

William Kellogg begins by describing his first acquaintance with the NCAR concept, and his belief in the benefits of team research or big science. He notes the first retreat meeting at Keystone and offers examples of problems that required an interdisciplinary approach. He mentions chairing a group for a larger study called the "Study of Critical Environmental Problems" ("SCEP" study for short), which wrote on human influences on climate, and discusses the challenges of getting scientists to work together, relating an anecdote about having to fire a dynamic meteorologist.
