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)

WANE4 West Africa Wind and Wave Hindcast Now Available

OWI are pleased to announce the availability of West Africa Normals and Extremes (WANE4), our latest publicly available hindcast for the West African coastline. This hindcast was designed to be an improvement over other available wind and wave datasets including ERA5 and our own previous WANE products.

These hindcast data consist of continuous hourly time steps of wind and wave parameters from 1979 through 2024, with yearly future updates. Full 2D frequency-directional wave spectra are also available along the entire coastline at a subset of archive locations. These data are suitable for a variety of uses in the metocean and offshore design fields, and are available for purchase by point or as a whole and in a variety of formats including statistical analyses.
