The climate data were collected between 1988 and 1995 and include portions of 25 volumes of fan-fold line-printer computer printouts, with 10 columns of variables per page. The legacy weather data was entered into Excel spreadsheets and delivered to the Arizona State Climate Office, Navajo Nation, and the Desert and Southern Rockies LCCs. This project was completed by the USGS Arizona Water Science Center in cooperation with the Navajo Nation.
