Meteoc-2 site visit to observe an example of site characterisation field work Agnieszka Bialek and Claire Greenwell of NPL visited the CNES site at La Crau, France, part of RadCalNet, a prototype network of automated vicarious satellite reference sites. This visit was one of four planned visits to RadCalNet prototype sites during the MetEOC 2 project,… Read More


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… Read More
