161. Uncertainty Budgets for Realization of ITS-90 by Radiation Thermometry
Published: 1/1/2003
Authors: J Fischer, M Battuello, M Sadli, M Ballico, S N Park, P Saunders, Y Zundong, Bettye C Johnson, E Van der Ham, F Sakuma, Graham Machin, N Fox, W Li, S Ugur, M Matveyev
Abstract: Recent international comparisons [1,2] and key comparisons have shown that the realization of the ITS-90 above the freezing point of silver and its dissemination may be less straightforward than expected. In many cases, the deviations of the local s ...

164. Vacuum Processing Technique for Development of Primary Standard Blackbodies
Series: Journal of Research (NIST JRES)
Published: 6/1/1999
Authors: Magdalena Navarro, Sally Skidmore Bruce, Bettye C Johnson, A V Murthy, Robert D. Saunders
Abstract: Blackbody sources with nearly unity emittance that are in equilibrium with a pure freezing metal such as gold, silver, or copper are used as primary standard sources in the International Temperature Scale of 1990 (ITS-90). Recently, a facility using ...

165. Validation of Radiometric Standards for the Laboratory Calibration of Reflected-Solar Earth Observing Satellite Instruments
Published: Date unknown
Authors: James J. Butler, Bettye C Johnson, Joseph Paul Rice, Steven W Brown, R Barnes
Abstract: Historically, the traceability of the laboratory calibration of Earth-observing satellite instruments to a primary radiometric reference scale (SI units) is the responsibility of each instrument builder. For the NASA Earth Observing System (EOS), a ...

166. Validation of the dissemination of spectral irradiance values using FEL lamps
Published: 9/27/2012
Authors: Bettye C Johnson, Gary D. Graham, Robert D. Saunders, Howard W Yoon, Eric L Shirley
Abstract: Scales of spectral irradiance are disseminated from NIST by assignment of values to FEL-type lamp standards for defined conditions. These lamp standards can be used for absolute calibration of irradiance radiometers, or more typically, be used in con ...

167. Volume 4, The 1997 Prelaunch Radiometric Calibration of Sea WiFS
Published: 4/1/1999
Authors: Bettye C Johnson, Howard W Yoon, Sally Skidmore Bruce, Ping-Shine Shaw, E A Thompson, S B. Hooker, R Eplee, R Barnes, S Maritorena, J Mueller
Abstract: The Sea-viewing Side Field-of-view Sensor (SeaWiFS) was originally calibrated by the instrument's manufacturer, Santa Barbara Research Center (SBRC), in November 1993. In preparation for an August 1997 launch, the Sea WiFS Project and the Nation ...
