SWIR calibration of spectralon reflectance factor

October 3, 2011
Catherine C. Cooksey, Georgi T. Georgiev, James J. Butler, Leibo Ding, Kurtis J. Thome
Satellite instruments operating in the reflective solar wavelength region require accurate and precise determination of the Bidirectional Reflectance Factor (BRF) of laboratory-based diffusers used in their pre-flight and on-orbit radiometric calibrations

NIST Measurement Services: Regular Spectral Transmittance

March 10, 2011
David W. Allen, Edward A. Early, Benjamin K. Tsai, Catherine C. Cooksey
This document describes measurement services, instrumentation, and measurement techniques for regular spectral transmittance over the spectral range from 250 nm to 2500 nm at the National Institute of Standards and Technology. Section 2 explains the basic

Workshop on Bridging Satellite Climate Data Gaps

February 16, 2011
Catherine C. Cooksey, Raju V. Datla
Detecting the small signals of climate change for the most essential climate variables requires that satellite sensors make highly accurate and consistent measurements. Data gaps in the time series (such as possible launch delay or failure) or

Terahertz spectroscopy of aqueous L-Proline in reverse micelles

November 21, 2008
Catherine C. Cooksey, Edwin J. Heilweil, Benjamin Greer
A new method for obtaining room temperature terahertz (THz) absorption spectra of aqueous-phase biomolecules in the frequency range 1 THz to 21 THz (35 cm-1 to 700 cm-1) is reported. The spectrum for L-Proline was acquired by solvating the amino acid
