Samoa Atmosphere Model

Samoa Atmosphere Model

Voyager now includes a new high resolution regional atmosphere model for the Samoan Islands region, including the islands of both American Samoa and (Western) Samoa. This Weather Research and Forecasting (WRF) mesoscale numerical weather prediction model provides hourly, 7-day forecasts of surface air temperature, wind, rain, humidity, and air pressure.

This model uses the Advanced Research WRF (ARW) dynamical solver developed and maintained by the Mesoscale and Microscale Meteorology Division of the National Center for Atmospheric Research (NCAR). Model runs are produced by Dr. Yi-Leng Chen of the Department of Meteorology in the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaiʻi at Mānoa and have been added today to the PacIOOS data servers. This complements our existing global NCEP GFS forecast as well as our WRF collections in Hawaiʻi, CNMI, and Guam.

These model results were generated as part of an academic research project. They provide a scientific prediction of current and future conditions. As with any forecast, however, accuracy cannot be guaranteed and caution is advised. While considerable effort has been made to implement all data components in a thorough, correct, and accurate manner, numerous sources of error are possible.

PacIOOS is the first regional association that was certified as a Regional Information Coordination Entity (RICE) by the U.S. Integrated Ocean Observing System (IOOS). Certification provides NOAA and its interagency partners a means to verify that a regional association’s organizational and operational practices, including data management, meet recognized and established standards set by NOAA.
