  PERGOS-3 Hindcast Available for the Persian Gulf Region

  We are pleased to announce the availability of PERGOS-3, Oceanweather's (OWI's) follow-up to the PERGOS and PERGOS-2 metocean hindcasts for the Persian Gulf. This continuous hindcast archive spans the period 1960 through 2024 and has been produced using our decades of experience in atmospheric reanalysis and ocean response modeling in the region. For the hindcast, the ADCIRC+SWAN modeling system was implemented in the relatively shallow Gulf domain to capture tidal and storm surge water level variation and incorporate it in the wave model response. Wind, pressure, bulk wave, water level and current parameters are available as time series at individual points in addition to available operability and extreme value analyses.

  • Archive Time Step: 1-hour
  • Hindcast Period: 1960-01-01 through 2024-12-31 (continuous)
  • Variables: Met., Wave and Hydro.
  • Spatial Resolution: 500m-6km (unstructured mesh)
  • Latitude Coverage: \(23.14^{\circ}\) to \(30.5^{\circ}\) N
  • Longitude Coverage: \(47^{\circ}\) to \(56.4^{\circ}\) E
  • Met. forcing: ERA5 with statistical corrections and kinematic analyses
  • Tidal boundary: TPXO9 forced from the Gulf of Oman
  • Previous Hindcasts:
    • PERGOS (2005) 1983-2009 (+ earlier storms)
    • PERGOS-2 (2018) 1979-2018 (+ earlier storms)
