Construct a quality-aware NEXRAD multi-radar mosaic from aligned single-site products with explicit coverage, beam geometry, quality weighting, overlap resolution, and provenance.

When to use

• Combine two or more radars to cover a region with overlapping or adjacent
• Construct a consistent base-reflectivity, velocity, spectrum-width, or
• Build a research mosaic on a common grid or for a cross-radar comparison.
• Compare a custom mosaic with an official MRMS product.
• Visualize source contributions and coverage gaps in a composite.

When not to use

• Heterogeneous range, beam width, terrain, calibration, and product processing
• A selection-based mosaic may create discontinuities or discard useful
• No pixel is an independent observation; quality and source fields are
• Custom mosaics require local validation and are not an official warning or
