EUM/OPS/VWG/11/0361GEWEX/GlobVapour Water Vapour Workshop Issue 1 05/03/2011 Plan for MVIRI and SEVIRI Infrared Intercalibration Use inter-calibrated HIRS from NOAA/NCDC (adjusted to HIRS on NOAA12) with GSICS collocation and inter-calibration procedures taking HIRS as truth; Control intercalibration using ARSA (Analyzed Radio Soundings Archive) database from LMD; Control intercalibration in overlapping areas after IODC start, e.g., Met-5 vs. Met-7; Derive AMV and other parameters from inter-calibrated radiance and document changes. Deliver both FCDR data and corrections to be applied by expert users (SAFs, ECMWF reanalysis); Need to implement common cloud detection (need one for both); Development and implementation targeted for 2011/2012; Longer Term: Implement inter-calibration based on IASI (based on GSICS and collaboration with projects in the NOAA CDR program)). Estimate potential and feasibility of further improving MVIRI level 1.5 by reanalysing the image archive. Slide: 7
