The Global Forecast System (GFS) is a weather forecast model produced by the National Centers for Environmental Prediction (NCEP). Dozens of atmospheric and land-soil variables are available through this dataset, from temperatures, winds, and precipitation to soil moisture and atmospheric ozone concentration. The entire globe is covered by the GFS at a base horizontal resolution of 18 miles (28 kilometers) between grid points, which is used by the operational forecasters who predict weather out to 16 days in the future.

The Rapid Update Cycle (RUC) weather forecast model was developed by the National Centers for Environmental Prediction (NCEP). On May 1, 2012, the RUC was replaced by NCEP's Rapid Refresh (RAP) weather forecast model. The RUC was designed to produce quick, short-term, weather forecasts using the most currently available observations. When it was first implemented in 1994, the model was run every three hours making forecasts out to 12 hours. By 2002, the RUC was run every hour, on the hour, producing 12-hour forecasts with a 1 hour temporal resolution.

This dataset is a compilation of in situ daily and hourly meteorological observations for the former USSR initially obtained within the framework of several joint projects of All-Russian Research Institute for Hydrometeorological Information-World Data Center of the Federal Service for Hydrometeorology and Environmental Monitoring, Obninsk, Russian Federation, and (former) NOAA National Climatic Data Center, Asheville, North Carolina.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Global Analysis report summarizes global observations of surface and upper-air temperature and precipitation data and places the data into historical perspective.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Global Hazards highlights significant weather-related hazards and disasters across the world. The reports focus on the following events: drought and wildfire, excessive temperatures, flooding, severe storms, tropical cyclones, extratropical cyclones, severe winter weather, polar events and sea ice, and ecosystem impacts.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview-National Overview summarizes observations of surface temperature and precipitation data for the United States by placing the data into historical perspective. The National Overview provides access to monthly, 3-month/seasonal, 6-month, 12-month and annual climate summaries by state, division and region.

The 14th Weather Squadron of the U.S. Air Force (USAF-14WS) creates a comprehensive dataset of weather observations; these observations stem from hundreds of domestic and international networks on a daily basis. Observations cover a broad spectrum of information that are incorporated into the NOAA Integrated Surface Data product.

Quality Controlled Local Climatological Data (QCLCD) contains summaries from major airport weather stations that include a daily account of temperature extremes, degree days, precipitation amounts and winds. Also included are the hourly precipitation amounts and abbreviated 3-hourly weather observations. The source data is global hourly (DSI 3505) which includes a number of quality control checks. The local climatological data annual file is produced from the National Weather Service (NWS) first and second order stations.
