1. Remote sensing of chiral signatures on Mars
Topic: Remote Sensing
Published: 11/1/2012
Authors: William Sparks, James H. Hough, Thomas Avery Germer, Frank Robb, Ludmilla Kolokolova
Abstract: We describe circular polarization as a remote sensing diagnostic of chiral signatures which may be applied to Mars. The remarkable phenomenon of homochirality provides a unique biosignature which can be amenable to remote sensing through circular ...

2. Lunar Spectral Irradiance and radiance (LUSI): new instrumentation to characterize the Moon as a space-based radiometric standard
Series: Journal of Research (NIST JRES)
Report Number: 117.011
Topic: Remote Sensing
Published: 7/17/2012
Authors: Allan W. Smith, Steven Ray Lorentz, Raju Vsnu Datla, Thomas C. Stone
Abstract: The need to understand and monitor climate change has led to proposed radiometric accuracy requirements for space-based remote-sensing instruments that are very stringent and currently beyond the reach of many Earth orbiting instruments. A major ...

3. Measurement of H2O-Broadening of O2 A-band Transitions and Implications for Atmospheric Remote Sensing
Topic: Remote Sensing
Published: 3/27/2012
Authors: E. M. Vess, C. J. Wallace, H. M. Campbell, V. E. Awadalla, Joseph Terence Hodges, David A Long, D. K. Havey
Abstract: We present laboratory measurements of H2O-broadened 16O2 A-band ( ) absorption spectra acquired with a laser-based photoacoustic spectroscopy method. This absorption band is widely used in a variety of high-precision atmospheric remote sensing appli ...

4. Workshop on Bridging Satellite Climate Data Gaps
Series: Journal of Research (NIST JRES)
Topic: Remote Sensing
Published: 2/16/2011
Authors: Catherine C Cooksey, Raju Vsnu Datla
Abstract: 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 incon ...

5. The Marine Optical BuoY (MOBY) Radiometric Calibration and Uncertainty Budget for Ocean Color Satellite Sensor Vicarious Calibration
Topic: Remote Sensing
Published: 10/31/2010
Authors: M Feinholz, Bettye C Johnson, Steven W Brown, S Flora, M Yarbrough, Terrance Houlihan, D Peters, Yong S. Kim, J Mueller, Dennis Clark
Abstract: For the past decade, the Marine Optical Buoy (MOBY), an autonomous radiometric buoy stationed in the waters off Lanai, Hawaii, has been the primary in-water oceanic observatory for the vicarious calibration of the U. S. satellite ocean color sensors ...

7. Report on the NIST workshop of December 10, 2009: calibration strategies for bridging possible climate data gaps
Topic: Remote Sensing
Published: 8/12/2010
Authors: Raju Vsnu Datla, Joseph Paul Rice, Catherine C Cooksey, Kurtis J Thome, Robert Barnes, Changyong Cao
Abstract: A one day workshop was held on December 10, 2009 at the National Institute of Standards and Technology to address the issue of data gaps in the time series of satellite measurements. Such gaps can occur due to launch delay or failure, or inconsisten ...

Topic: Remote Sensing
Published: 4/26/2010
Authors: Ian R Coddington, William C Swann, Nathan Reynolds Newbury
Abstract: Time-domain spectroscopy using dual, coherent frequency combs is used to measure free-induction decay from a molecular gas sample in the near-IR with a time-domain signal-to-noise ratio of ~10^u6^ over a ~6 ns window at 55 fs time resolution (corresp ...
