A stabilized finite volume method for solving the transient Navier– Stokes equations is developed and studied in this paper. This method maintains conservation property associated with the Navier–Stokes equations. An error analysis based on the variational formulation of the corresponding finite volume method is first introduced to obtain optimal error estimates for velocity and pressure. This ...

An analytical expression for the variance of the radiance measured by Fourier-transform infrared (FTIR) emission spectrometers exists only in the limit of low noise. Outside this limit, the variance needs to be calculated numerically. In addition, a criterion for low noise is needed to identify properly calibrated radiances and optimize the instrument bandwidth. In this work, the variance and t...

[1] A Fourier Transform Infrared (FTIR) spectroradiometer was deployed at Palmer Station, Antarctica, from 1 September to 17 November 1991. This instrument is similar to the Atmospheric Emitted Radiance Interferometer (AERI) deployed with the U.S. Department of Energy Atmospheric Radiation Measurement (ARM) program. The instrument measured downwelling zenith radiance in the spectral interval 40...

This work describes in situ moisture sensor comparisons performed in conjunction with the first Water Vapor (WV) Intensive Observation Period (IOP) conducted at the Atmospheric Radiation Measurement (ARM) Program Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site during September of 1996. Numerous remote sensing instruments (e.g., two Raman Lidar, two Atmospheric Emitted Radian...

The Society of American Archivists (SAA), North America's oldest and largest national professional archives association, has dramatically strengthened its infrastructure for research innovation in the last few decades, believing, as former SAA Executive Director Nancy Beaumont explained, “that practice, education, informs other. Each can—and should—improve other, each is critically important to...
