What AI says about SWDI Interactive Map

The SWDI is a unified US database of severe weather records from NOAA/NCEI and partner sources that supports searching by location and time and downloading results in multiple formats (CSV, JSON, XML, Shapefile, KMZ). It provides datasets such as Filtered Storm Cells, All Storm Cells, Hail Signatures, Mesocyclone Signatures, Digital Mesocyclone Detection, Tornado Signatures, and Lightning Strikes, derived from NEXRAD Level-III products and Vaisala NLDN data, with bulk CSV downloads available. SWDI does not add quality control beyond archival processing, and data may be incomplete or radar-derived, with coverage varying by location and time.
