Data-Based Models for Global Temperature Variations

Author(s)
Bert W. Rust, Barend J. Thijsse
This paper presents two data-based models for the measured time series of global annual average tropospheric temperatures. One model is a smoothing spline fit

SEMPA Imaging for Spintronics Applications

Author(s)
John Unguris, Daniel T. Pierce, Seok-Hwan Chung
Scanning Electron Microscopy with Polarization Analysis (SEMPA) provides high resolution (10 nm) magnetization images simultaneously with, but independent of

Effects of the Rooftop Environment on GPS Time Transfer

Author(s)
Michael A. Lombardi, Andrew N. Novick
We examine the effects of the rooftop environment on GPS time transfer, in particular the effects of multipath reflections from nearby metallic objects. Three

Long-term Stability of NIST Chip-Scale Atomic Clock Physics Packages

Author(s)
Svenja A. Knappe, V Shah, Vladislav Gerginov, Alan Brannon, Leo W. Hollberg, John E. Kitching
We present measurements regarding the long-term frequency instability of NIST CSAC physics packages. Changes of the clock frequency are caused mainly through

GPS Signal Integrity Dependencies on Atomic Clocks

Author(s)
Marc A. Weiss, Pradipta Shome, Ron Beard
The problem of signal integrity for GPS satellites is discussed. In particular, there is a need for characterizing peak deviation of GPS clocks from prediction
