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.

The Global Forecast System (GFS) CPEX dataset includes model data simulated by the Global Forecast System (GFS) model for the Convective Process Experiment (CPEX) field campaign. The NASA Convective Processes Experiment (CPEX) aircraft field campaign took place in the North Atlantic-Gulf of America-Caribbean Sea region from 25 May-25 June 2017. CPEX conducted a total of sixteen DC-8 missions from 27 May-24 June. The CPEX campaign collected data to help explain convective storm initiation, organization, growth, and dissipation in the North Atlantic-Gulf of America-Caribbean Oceanic region during the early summer of 2017. These data are available from May 24, 2017 through July 20, 2017 and are available in netCDF-3 format.
