Abstract

The North American Mesoscale Forecast System (NAM) is one of the primary vehicles by which NCEP's Environmental Modeling Center provides mesoscale guidance to public and private sector meteorologists.

It consists of the NOAA Environmental Modeling System (NEMS) version of the Non-Hydrostatic Multi-scale Model in B-grid (NMMB) and the NCEP regional Grid-Point Statistical Interpolation (GSI) analysis. The NAM is initialized with a 12-hour run of the NAM Data Assimilation System, which runs a sequence of four GSI analyses and 3-hour NEMS-NMMB forecasts using all available observations to provide a first guess to the NAM on-time analysis.

This NAM Hawaii nested product provides a 60-hour forecast at hourly and 3-hourly time steps at a 3 km resolution. The model is run four times daily at 00z, 06z, 12z, and 18z. [More...]

Description

At the moment 00z run is available at Planet OS Datahub. If you are interested in 06, 12 or 18 runs, please let us know!
