U.S. National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) numerical weather prediction model 8-day, 3-hourly forecast for the globe at approximately 50-km or 0.5-deg resolution.

U.S. National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) numerical weather prediction model 8-day, 3-hourly forecast for the globe at approximately 50-km or 0.5-deg resolution.

Weather Research and Forecasting (WRF) mesoscale numerical weather prediction model 7-day hourly forecast for the region surrounding the island of Guam at approximately 3-km resolution. 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 produced at the University of Hawaii by Yi-Leng Chen.

The Weather Analyses and Forecasts Charts from the NOAA National Weather Service (NWS) National Centers for Environmental Prediction (NCEP) are produced on a daily basis at meteorological synoptic times, normally at 00 and 12 UTC. Chart contents contain constant pressure charts, including the analyses and forecasts of heights, temperatures, winds, relative humidity, vertical velocity, vorticity, lifted index, thickness levels, and wind shear. Also available are surface analyses and charts of the Atlantic and Pacific with special emphasis on specific areas such as the Gulf of Alaska. The geographic coverage of includes the Northern and Southern Hemispheres, Tropical and Polar Regions. The charts are represented in 6-bit binary, TIFF, JPEG and GIF image file formats over the period of record from February 1994 to the present.
