Exploring convective storms with MTG FCI

Flexible Combined Imager (FCI) of the Meteosat Third Generation – Imager (MTG-I) satellites provides significant improvement of observational capabilities over its predecessor, Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument of Meteosat Second Generation (MSG) satellites. The present work focuses on some of the convective storms related phenomena or features, which were either beyond or on the edge of SEVIRI observations, benefiting from the new spectral bands and improved spatial resolution of FCI, namely in the High Resolution (HR) bands.The study will address, among other, detailed cold ring and/or cold U/V features structure, convective low level outflows (including undular bore cases), Above Anvil Cirrus Plumes (AACP), Brightness Temperature Difference (BTD) of WV absorption and IR window bands, and storm top gravity waves – depending on storms available from the 2024 and 2025 convective seasons. Selected FCI cases will be compared to corresponding SEVIRI images or image products, in order to document the added value of FCI. Alternatively, these will also be compared to high resolution observations from instruments of some of the low Earth orbit satellites, such as VIIRS (Visible Infrared Imaging Radiometer Suite) of S-NPP, NOAA-20 and NOAA-21, and MODIS (Moderate Resolution Imaging Spectroradiometer) of Terra and Aqua, where available.
