Grib File

Weather in TIMEZERO

The GRIB file (General Regularly distributed Information in Binary form) is a format for weather data that can be compacted into a small file. The data includes the wind, waves, rain, pressure, air temperature, currents and more. This weather can be displayed directly in your navigation software represented in the form of isolines, arrows and a color scale.

The high level of resolution allows you to visualize the different weather data precisely in close detail at any given time, hour and date up to 16 days in advance.

World Meteorological Organisation

The WMO is an organization developed by the United Nations and has existed since 1951. Their role is to standardize the weather forecasts and meteorological measures. The GRIB files that are downloadable from TIMEZERO software are therefore in accordance with this standard. Specialized in climate and weather, operational hydrology and related geophysical sciences.
