Northeast Pacific Regional Climatology version 2 (NCEI Accession 0303733)

browse graphicPreview graphic
The Northeast Pacific (NEP) Regional Climatology (RC) version 2 replaces the previous version of the NEP RC published in 2017. Version 2 based on the recently released World Ocean Database (WOD23), and covers a time period from 1955 to 2022.

The updated high-resolution temperature and salinity climatologies allow researchers to assess decadal ocean climate change more precisely in the critically important NEP region. The updates substantially increase the value of the NEP RC for ocean climate studies and other applications.

The NEP is one of the most productive ecosystems in the World Ocean, home to the California Current System (CCS) and a large coastal upwelling zone along the west coast of North America. The economic and climatic importance of the CCS has prompted intensive observation and research over the decades, yielding rich oceanographic data arrays of the area and its adjacent regions.
