SailGrib renews its GRIB model offering

The latest version of SailGrib WR arrives with a completely revised list of weather and ocean models in order to allow users to benefit from the evolution of the offer of international forecast models. The number of models offered increases with new models and the addition of new resolutions available for certain models). Some models evolve and others are added. The version beta is already online.

Evolving Global weather models

• GFS adds a time step of 1 hour at the four steps already available (3, 6, 9, 12 hours).

• ECMWF IFS now offers three resolutions 0.25°, 0,4° and 1°, four time steps (3, 6, 9, 12 hours) and four data : medium wind, pressure, precipitation and air temperature.

• ECMWF AIFS, European experimental model based on Machine Learning (IA), arrives in the three applications with two resolutions 0.25° and 1°, and three time steps (6, 9, 12 hours). Same data as IFS.

• ICON GLOBAL now proposes four resolutions : 0,125°, 0,25°, 0,5° and 1°, with the same five time steps as the GFS.

• GDPS (ex GEM) : the Canadian model increases its resolution from 0.24° to 0.15° and its timespan from 6 up to 10 days with four time steps (3, 6, 9, 12 hours).

• ARPEGE Monde increases from 0.5° to 0.25° with four time steps (3, 6, 9, 12 hours).

 

Evolving Regional weather models

• ARPEGE Europe now offers five time steps (1, 3, 6, 9, 12 hours).

 

• ICON Europe now offers five time steps (1, 3, 6, 9, 12 hours).

New Regional weather models

• HRRR CONUS covers the United States as the NAM, but with a very high resolution of 0.025° (1,5MN). Updated every hour, with 1 -hour steps and range up to 18 hours.

• ICON D2 covers part of Western Europe with a very high resolution of 0.02° (1,2MN) with 1 hour until 24 hours, no 3 hours until 48 hours. It is updated every three hours.

• UKV : British MetOffice model (UKHO) at very high resolution of 0.05° covering the southern coasts of the British Isles within 5 days per step 1, 3, 6, 9, 12 hours, updated twice a day, with wind at 10 meters and gusts.

Evolving Ocean models

  • Waves

• GFS WAVE : the former WW3 model by FNMOC is now assimilated to the GFS weather model (¹), with identical characteristics (resolutions, range, steps, updates).

MFWAM Global comes with several time steps like the ARPEGE Monde model

  • Currents

• COPERNICUS : the name “MyOcean” for current models disappears. Covers and features remain the same : Global, IBI, ENWS, Baltic, MED.

New ocean models

• HYCOM (Global) : high resolution ocean currents 0.08°, and low resolutions 0.25° and 0.5°, with 3 -hour steps and range up to 7 days.

• Copernicus SMOC : new global model of combined tidal and ocean currents, high resolution of 0.083°(5MN), 0,25°(15 MN) et 0,5°(30 MN) with 1-hour steps. and range up to 120 hours.

• WCPS Saint Laurent, Canadian model of CMC, covers the St. Lawrence with a 0.5MN grid, with 1 -hour steps and range up to 84 hours. Data provided : average wind at 10 meters and currents.

• IFREMER : currents at very high resolutions, with a grid up to 250 meters on the west and north coasts of France. With 1 -hour steps and range up to 100 hours.

• IFREMER WW3 : combination of wave and current data for the west and north coasts of France, at very high resolutions. With 1 -hour steps and range up to 100 hours.

Back-office

A new server infrastructure is implemented, in partnership with Weather4D, to support this change. They are calibrated for a significant increase in downloads, the increase in resolutions, and the integration of very high resolution current files. These high-availability servers are spread over three locations, an automatic failover process to ensure continuity of service. Improved procedures for downloading and checking input files should improve the quality of GRIB output to users..
