Achieving Climate Change Absolute Accuracy in Orbit

October 28, 2013
Author(s)
Bruce Wielicki, Joseph P. Rice
The Climate Absolute Radiance and Refractivity Observatory (CLARREO) mission will provide a metrology laboratory in orbit for the purpose of accurately measuring and attributing climate change. CLARREO measurements establish new climate change benchmarks

SORCE SSI Workshop Summary

July 1, 2012
Author(s)
Joseph P. Rice, Jerald Harder, Martin Snow, Thomas Woods
Over 30 scientists and calibration specialists gathered at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, for the first Solar Spectral Irradiance (SSI) Variations Workshop, Feb. 28-March 1, 2012. The purpose of the

Developing digital tissue phantoms for hyperspectral imaging of ischemic wounds

May 18, 2012
Author(s)
David W. Allen, Jeeseong Hwang, Maritoni A. Litorja, Joseph P. Rice
Biomedical optical imaging has the potential to achieve high spatial resolution and high functional sensitivity for non-invasive assessment of ischemic wounds. However, clinical acceptance of many optical imaging devices is hampered by poor reproducibility

Hyperspectral Image Projector Applications

February 15, 2012
Author(s)
Joseph P. Rice, Steven W. Brown, David W. Allen, Howard W. Yoon, Maritoni A. Litorja, Jeeseong Hwang
For the past several years NIST has been developing, along with several collaborators, a Hyperspectral Image Projector (HIP). This scene projector produces high-resolution programmable spectra and projects them into dynamic two-dimensional images. The

Best Practice Guidelines for Pre-Launch Characterization and Calibration of Instruments for Passive Optical Remote Sensing

November 1, 2009
Author(s)
Raju V. Datla, Joseph P. Rice, Keith R. Lykke, Bettye C. Johnson, James J. Butler, Xiaoxiong Xiong
The pre-launch characterization and calibration of remote sensing instruments should be planned and carried out in conjunction with their design and development to meet the mission requirements. In the case of infrared instruments, the onboard calibrators

Sources of Differences in On-Orbit Total Solar Irradiance Measurements

July 13, 2009
Author(s)
James J. Butler, R Barnes, B. Carol Johnson, Joseph P. Rice, Eric L. Shirley
There is a 5 W/m2 difference between current on-orbit Total Solar Irradiance (TSI) measurements. On 18-20 July 2005, a workshop was held at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland that focused on understanding

Hyperspectral Image Compressive Projection Algorithm

June 1, 2009
Author(s)
Joseph P. Rice, Jorge E. Neira, David W. Allen
We describe a compressive projection algorithm and quantitatively assess its performance when used with a Hyperspectral Image Projector (HIP). The HIP is being developed by NIST for system-level performance testing of hyperspectral and multispectral
