Advancements in SEVIRI HRV Channel for Meteorological Observations and Analysis

The SEVIRI High-Resolution Visible (HRV) Channel on Meteosat Second Generation satellites offers superior monitoring of small-scale meteorological features with a spatial resolution of 1 km. This paper discusses the channel's applications, including improved wind vector retrieval and fine-scale structure monitoring. It includes comparisons of data from the MSG HRV channel with previous versions and other satellite systems, demonstrating its capacity to observe cloud formations, atmospheric phenomena, and environmental changes across Europe and Africa, facilitating enhanced weather forecasting.
