As a child on a Navajo reservation in Arizona, Carl Etsitty was both profoundly respectful of nature, declaring to Mother Earth that “I will forever be a steward of the land.” His reverence for the environment was paired with intense curiosity, but those attitudes clashed in the early 1990s when Etsitty went to college.

New branches of NCAR research sometimes emerge through the advent of new technology, a change in national priorities, or a disastrous weather event. Other research topics have threaded their way through the center’s entire half-century history.

A team of scientists is tackling a scenario that is the stuff of Hollywood thrillers: What happens if a medium-sized asteroid strikes Earth? In particular, what if it crashes into the ocean? The question is not fanciful.

From its inception, NCAR provided a wide range of research-oriented computing and observing facilities. The initial focus was on centralized capabilities: networking was virtually nonexistent, and the huge cost of computers constrained university use.

Scientists in the UCAR community found themselves on the front lines of the cyber revolution that stormed the world in the 1990s. Many UCAR universities were early adopters of the World Wide Web, a technology well suited to a science that thrives on distributed data and collaboration.
