Basic radar products provide a wide range of grid data for ground-level precipitation, thunderstorms and other convection phenomena.
The following types of data are available:
- PRECIP: estimates of ground-level precipitation
- PRECIP-SV: estimates of ground-level precipitation with lateral projection
- MAX-ECHO: maximum reflectivity
- ECHO-TOP 14/45: maximum height of radar echo for 15 and 45 dBZ
All basic radar products cover the same region, namely Switzerland and neighbouring regions. The five-minute update rate of these products, together with their fast computation speed, makes them suitable for nowcasting systems with high spatial and temporal frequency. They provide basic information for estimates of ground-level precipitation and thunderstorms.
