34. Calibration and Characterization of Trap Detector Filter Radiometers
Published: 11/1/2003
Authors: David W Allen, George P Eppeldauer, Steven W Brown, E A. Early, Bettye C Johnson, Keith R Lykke
Abstract: We describe the development of a mechanically simple, radiometrically stable transfer radiometer designed for both radiance and irradiance measurements. The filter radiometer consists of a six-element Si trap detector, a temperature stabilized filter ...

35. Comparison of Laser-Based and Conventional Calibrations of Sun Photometers
Published: 11/1/2003
Authors: N Souaidia, C Pietras, G Fargion, R Barnes, R Frouin, Keith R Lykke, Bettye C Johnson, Steven W Brown
Abstract: Sun photometers are used to characterize the radiative properties of the atmosphere. They measure both the incident solar irradiance as well as the sky radiance (from scattered incident flux). Global networks of sun photometers provide data product ...

36. A Method for Testing the Spectral Responsivity of Infrared Cameras Using Tunable Lasers
Published: 8/1/2003
Authors: Joseph Paul Rice, Keith R Lykke, Howard W Yoon
Abstract: We are developing a technique for accurately measuring spectral responsivity functions of infrared cameras using tunable lasers. We present preliminary results for uniform scenes where tunable infrared lasers illuminate an integrating sphere, diffus ...

37. Quantum Yield of the Iodide/Iodate Chemical Actinometer: Dependence on Wavelength and Concentration
Published: 8/1/2003
Authors: R O Rahn, M I Stefan, J R Bolton, E Goren, Ping-Shine Shaw, Keith R Lykke
Abstract: The quantum yield (QY) of the iodide/iodate chemical actinometer (0.6 M KI/ 0.1 M K103) was determinedirradiation between 214 run and 330 mu. The photoproduct, triiodide, was determined flum the increase iabsorbance at 352 run, which together with a ...

39. Stray-Light Correction of the Marine Optical Buoy
Published: 6/1/2003
Authors: Steven W Brown, Bettye C Johnson, S Flora, M Feinholz, M Yarbrough, R Barnes, Y S Kim, Keith R Lykke, D K Clark
Abstract: In ocean-color remote sensing, approximately 90% of the flux at the sensor originates from atmospheric scattering, with the water-leaving radiance contribution the remaining 10 % of the total flux. Consequently, errors in the measured top-of-the atm ...

40. Radiometric Characterization and Absolute Calibration of the Marine Optical System (MOS) Bench Unit
Published: 3/1/2003
Authors: C Habauzit, Steven W Brown, Keith R Lykke, Bettye C Johnson, M Feinholz, M Yarbrough, D K Clark
Abstract: The Marine Optical Spectrograph (MOS) is a dual CCD-based spectrograph system developed for in-water measurements of down-welling solar irradiance, {Epsilon}^dd^, and up-welling radiance, L^du^. These measurements are currently used in the calibratio ...
