4. GIST 22 @ RMIB, Brussels; 8-10 November 2004 Page 4 MTG Missions Based on the assessment of observing techniques, five candidate observation missions identified for MTG  Three distinct imagery missions dedicated to operational meteorology, with emphasis on nowcasting and very short term forecasting: -The High Resolution Fast Imagery (HRFI) mission, enhancement of the MSG HRI mission; -The Full Disk High Spectral resolution Imagery (FDHSI) mission, successor to the MSG SEVIRI mission; -The Lightning Imagery (LI) mission;  An Infrared Sounding (IRS) mission focussed on operational meteorology, with some potential relevance to atmospheric chemistry;  An UV/Visible sounding (UVS) mission dedicated to atmospheric chemistry
