Update to the OPERA–SEVIRI fusion dataset

We are pleased to announce the addition of ground-based lightning-observation data from the NORDLIS network, which covers Northern Europe and contain all observed cloud-to-ground and intra-cloud strikes.

The new lightning dataset provides:

• exact strike locations and timestamps (Parquet files)

• strike counts aggregated to the same grid as the OPERA and SEVIRI data
