91. Achieving Satellite Instrument Calibration for Climate Change (ASIC3)
Published: Date unknown
Authors: Gerald T Fraser, Raju Vsnu Datla
Abstract: The Workshop on Achieving Satellite Instrument Calibration for Climate Change (ASIC3) was a follow-up to a 2002 Workshop (Ohring et al., 2004; Ohring et al., 2005) that had developed the measurement requirements for a number of global climate variabl ...

92. Analysis of Point-Contact Andreev Reflection Spectra in Spin Polarization Measurements
Published: Date unknown
Authors: G T Woods, Robert J. Soulen, I I Mazin, B Nadgorny, M. S. Osofsky, J Sanders, H. Srikanth, William F. Egelhoff Jr., Raju Vsnu Datla
Abstract: We present a systematic analysis of point-contact Andreev reflection (PCAR) spectra for ferromagnetic materials, using both modeling and experimental data. We emphasize the importance of consistent data analysis to avoid possible misinterpretation of ...

Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7199
Published: Date unknown
Authors: Adriaan Carl Linus Carter, Raju Vsnu Datla
Abstract: This NIST Low Background Infrared (LBIR) Calibration facility has become a national center for the development and dissemination of absolute standards and their traceability for the measurement of low level infrared radiation. The five year (FY 05 to ...

94. Measurement of Small Apertures
Published: Date unknown
Authors: James A Fedchak, Adriaan Carl Linus Carter, Raju Vsnu Datla
Abstract: The Low Background Infrared calibration (LBIR) facility at the National Institute of Standards and Technology (NIST) is developing a relative aperture area instrument to measure the areas of apertures with diameters ranging from 5 mm to 0.05 mm. NIS ...

95. Measurement of Thermophysical Properties for Future Development of Cryogenic Radiometers
Published: Date unknown
Authors: Z M Zhang, Steven Ray Lorentz, Joseph Paul Rice, Raju Vsnu Datla
Abstract: We have measured the thermal conductivity of polyimide at temperatures from 2.4 K to 8 K, and specific heats of polyimide and a black paint at 2.4 K and 4.4 K. It is shown that the responsivity and time response of cryogenic radiometers can be signi ...

97. Satellite Instrument Calibration for Measuring Global Climate Change
Series: NIST Interagency/Internal Report (NISTIR)
Published: Date unknown
Authors: G Ohring, B Wielicki, R Spencer, W Emery, Raju Vsnu Datla
Abstract: Measuring the small changes associated with long-term global climate change from space is a daunting task. The satellite instruments must be capable of observing atmospheric temperature trends as small as 0.10 degrees C / decade, ozone changes as lit ...
