Ambient Noise Interferometry

Dvv History

Retrieve the network-median dv/v series for the station pairs near a point.

Pricing: Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing). Requires authentication.

Served ONLY from the fixed method (in production since 2026-10-14; rs_network/dvv_fixed_reader.py). Each date is the MEDIAN over at least 10 station pairs, a 14-day moving average, in the deep (0.1-0.5 Hz) or mid (0.5-2 Hz) band, 90-day reference window. Rows computed by the earlier pipeline are never served: the answer is null with the reason and a count of what was withheld. The validation claim is in dvv_validation: validated for network-level drops after large earthquakes only. (Until 2026-10-14 a miss became a seeded random-walk "modeled estimate".)
