Listing of GRIB and other objective forecasts

Updated January 2018.

About this page

A list of many GRIB and similar services, whether received by email, FTP (File Transfer Protocol) directly downloading to a PC or tablet or on a web browser.

This page will help users to decide which is best for them. I am trying to keep up to date with the many services that are becoming available and the page will never be up to date, but it will be a start for many,

List of Services

This is a listing of GRIB and similar services. Most large area forecasts are taken directly from the US NOAA GFS (Global Forecast System.) Alternatives are the CMC GEM (Canadian Global Environmental Model) and the US Navy NAVGEM . The GFS uses a grid spacing of 0.125 degree but provides GRIB data On a 0.25 degrees grid, about 25 km. Others may only give data on a 0.5 degree grid. Some viewers interpolate to finer grids and give a false impression of resolution.

ECMWF (European Centre for Medium-range Weather Forecasts) and the UK UM (Unified model) run global models on grid of 0.1 degree, 10 or 11 km. These two leading global models are not freely available. ARPEGE is the Météo France global model and is now available in GRIB format. WW3 is the US Wave model based on the GFS.


Forecasts on finer scales are referred to as “Meso-scale” or “LAM” (Limited Area.Models.) These include:

  • COAMPS – a US Navy weather model. Resolution about12 km.
  • WRF – a US Weather Research and Forecast Model used by several "non-official" groups, Usually about 12 km WRF is a successor to the ETA model.
  • Skiron is a University of Athens model based on the ETA but using a 0.05 degree (~5 km) grid
  • HIRLAM – used by several European countries. Resolution down to about 2 km.
  • UK4 covers from mid-Atlantic to the Urals on a 4 km grid. UKV, a British Isles 1.5 km model.
  • ALADDIN. A Météo France model
  • AROME. A Météo France limited area model
  • HARMONIE. Similar to HIRLAM. Developed in association with AROME.

There are many more.

NOTE

Limited area/meso-scale forecasts

National weather service limited area models start with detailed data analyses to produce detailed short period forecasts. This requires access to and the ability to process masses of data from space and terrestrial based observing systems. As far as I am aware, no other producer of Numerical Weather Prediction Model output (GRIBs) has the ability to do so. Although their models can handle topographic effects well their forecasts will suffer by lack of detailed meteorological data.
