In this work we examine the user behavior of the National Center for Atmospheric Research’s (NCAR) archive. In particular we characterized user sessions and examined namespace locality of accesses within those sessions. Preliminary results suggest within a single session, repeat file accesses are uncommon, and that accessed files are localized within a small set of directories. This work provid...

This project proposes a low-cost balloon observation system for sustained (in time), broadly distributed (in space), in-situ (between 1-8km altitude), real-time measurement (from data acquisition to NCAR within 20 minutes) of hurricane development. The high density measurements from such a robotic vehicle swarm will be invaluable in significantly improving our ability to estimate and forecast s...

This paper describes a quasi-operational regional air quality forecasting system for the contiguous United States (CONUS) developed at National Center Atmospheric Research (NCAR) to support decision-making, field campaign planning, early identification of model errors and biases, atmospheric science community in their research. aims complement operational forecasts produced by Oceanic Administr...

As part of the Intercomparison of Radiation Codes in Climate Models (ICRCCM) project, careful comparisons of the performance of a large number of radiation codes were carried out, and the results compared with those of benchmark calculations. In this paper, we document the performance of a number of parameterized models which have been heavily used in climate and numerical prediction research a...
