operational flight planning needs.
WMO GRIB Flight Planning data includes flight planning u
and v wind components and temperature field forecasts in support of
aircraft operations. Additional meteorological fields are included such as
geopotential heights, humidity, vertical velocity and precipitation for
Regional Area Forecast Center use in preparing guidance materials such as
significant weather chart preparation and general forecast operations.

Aeronautical/Operational Meteorological (OPMET) data includes the following data for flight planning.
Charts and Graphics data includes the information to satisfy the
