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
