The Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA) is a German airborne imaging FTS (Fourier Transform Spectrometer) capable of operating on various airborne platforms for sensing dynamics and chemistry of the UTLS (Upper Troposphere and Lower Stratosphere) region. The instrument is a joint development of the research centers KIT (Karlsruher Institut für Technologie) and the Forschungszentrum (Research Center) Jülich. The University of Wuppertal is also a partner in the project. GLORIA uses a two-dimensional detector array for infrared limb-observations. The GLORIA in-flight calibration system consists of two identical large-area high-precision blackbodies, which are independently controlled at two different temperatures. Thermo-Electric Coolers are used to control the temperature of the blackbodies. As reported in the paper (paywall), the system …

G. Zibordi, K. Ruddick, I. Ansko, G. Moore, S. Kratzer, J. Icely, and A. Reinart of JRC had their paper In situ determination of the remote sensing reflectance: an inter-comparison published on 6 August 2012 in Ocean Sciences magazine. Koppmann, R., F. Olschewski, P. Steffens, C. Rolf, P. Preusse, A. Ebersoldt, F. Friedl-Vallon, A. Kleinert, C. Piesch, J. Hollandt, B. Gutschwager and C. Monte of PTB and BUW presented the paper  at the International Radiation Symposium this month in Berlin, Germany. The paper summarises results from a radiometric inter-comparison performed in the northern Adriatic Sea with the main objective of evaluating the agreement of in situ spectral remote sensing reflectance products determined through the application of independent measurement systems and methods. The …

PTB reports on the spectral radiance, radiance temperature and emissivity measurements by instrumentation for radiation thermometry and emissivity measurement under vacuum and in a liquid nitrogen cooled environment at its Reduced Background Calibration Facility (RBCF), for the Ninth International Temperature Symposium. AIP Conference Proceedings (restricted access): C. Monte, B. Gutschwager, A. Adibekyan, M. Kehrt, F. Olschewski, J. Hollandt of PTB and BUW present ‘Radiation thermometry for remote sensing at PTB‘ at the Ninth International Temperature Symposium. PTB is extending, improving and characterising its Reduced Background Calibration Facility in MetEOC.
