5. Slide: 5 10 October 2014 Common Reference Channels T. Hewison provided a short presentation on his work performed on common reference channels. These might be useful to generate a composite dataset – e.g. for visualisation purposes. The performed analysis on IR channels showed that the spectral conversion dominates the error budget. For VIS channels, the concept will be even more problematic. During the discussion it was questioned whether a real user requirement for such a product exists, noting the already performed activities. It was agreed to inform users at the next Users’ Workshop on these already ongoing activities to find out whether any user requirement exists which is not covered.

6. Slide: 6 10 October 2014 Strategy for LEO-LEO Inter-calibration LEO-LEO reference instruments could be IASI, AIRS, MODIS, GOME-2, and others. Applicable inter-calibration methods are SNOs, regional band normalisation, double differencing against NWP. It is noted that many activities have started in the past and are still ongoing in the area of LEO-LEO inter-calibration. The group concluded that the GRWG strategy here would be to review users’ requirements, identify already existing inter-calibration activities which meet these requirements and invite the relevant groups to submit their products for GSICS acceptance. GSICS users will be informed about this strategy. No.TitleActionee(s)Due Date Action GRWG06_22 Inform users on the adopted strategy for LEO- LEO inter-calibration T.
