Her NCAR career began in 1967 when she joined the Personnel Department (now Human Resources). In 1979, she changed direction and started work for Warren Washington as a data an- alyst in the Climate Sensitivity & CO2 Research Group (under a Department of Energy contract) and then moved forward to a programming position with the same group. Her twenty-six years at NCAR (minus a couple of years' hiatus) was a • period oflearning new jobs and perfecting perfor- I mance. She has been an integral part of the wide range of activities that are. so necessary to the· success of an organization like NCAR-working with its people and contributing to the end product of their efforts-the science. Thanks, Lynda, and goodbye.
