Subsurface Cross Correlate

Compute noise cross-correlation between a station pair.

Downloads ambient noise records for two stations, applies spectral whitening and temporal normalization, then computes the cross-correlation to extract the empirical Green's function (EGF). Pricing: Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).

Parameters (JSON body):

  • station_pair : list[str] -- Two station codes (required)
  • start_date : str -- Start date ISO 8601 (required)
  • end_date : str -- End date ISO 8601 (required)
  • freq_min : float -- Minimum frequency in Hz (optional, default 0.05)
  • freq_max : float -- Maximum frequency in Hz (optional, default 0.5)
