Service Records and Retention System (SRRS) is historical digital data set DSI-9949, a collection of products created by the U.S. National Weather Service (NWS) and archived at the National Centers for Environmental Information (NCEI) [formerly National Climatic Data Center (NCDC)]. SRRS was a network of computers and associated hardware whose purpose was to transmit and store a large number of NWS products and make them available as needed.

U.S. Monthly Climate Normals (1971-2000) (DSI-9641C) include climatological normals based on monthly maximum, minimum, and mean temperature and monthly total precipitation records for each year in the 30-year period 1971-2000. DSI-9641G include climatological normals based on monthly and annual heating and cooling degree days. In order to be included in the normals, a station had to have at least 10 years of monthly temperature data or 10 years of monthly precipitation data for each month in the period 1971-2000.

The U.S. Daily Climate Normals (DSI-9641D) are based on monthly maximum, minimum, and mean temperature and monthly total precipitation records for each year in the 30-year period 1971-2000, inclusive (as well as separately computed monthly degree day totals). The monthly values are available in data set DSI-9641C or publication online (Climatography of the United States, No. 81 Monthly Station Normals of Temperature, Precipitation, and Heating and Cooling Degree Days, 1971-2000).

Local Climatological Data (LCD) 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. This is the final quality controlled copy and generally has a one to two month time lag. The local climatological data annual file is produced from the National Weather Service (NWS) first and second order stations. These data are contained in the LCD monthly and annual publications.

Hourly Precipitation Data (HPD) is digital data set DSI-3240, archived at the National Climatic Data Center (NCDC). The primary source of data for this file is approximately 5,500 US National Weather Service (NWS), Federal Aviation Administration (FAA), and cooperative observer stations in the United States of America, Puerto Rico, the US Virgin Islands, and various Pacific Islands. The earliest data dates vary considerably by state and region: Maine, Pennsylvania, and Texas have data since 1900.

This dataset consists of Level II weather radar data collected from Next-Generation Radar (NEXRAD) stations located in the contiguous United States, Alaska, Hawaii, U.S. territories and at military base sites. NEXRAD is a network of 160 high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force (USAF).

Year 2001 Tropical Cyclones of the World poster. During calendar year 2001, fifty tropical cyclones with sustained surface winds of at least 64 knots were observed around the world. NOAA's Polar-Orbiting Operational Environmental Satellites (POES) captured these powerful storms near peak intensity, which are all presented in this colorful poster. Poster size is 36"x 36".

This dataset includes one-minute observations for visibility extinction coefficient, 2-minute average and 5-second peak wind speed and direction, and runway visual range for approximately 900 stations in the U.S., Puerto Rico, the U.S. Virgin Islands, and some Pacific island territories as part of the Automated Surface Observing Systems (ASOS) network. The ASOS Program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD).

This dataset includes one-minute observations for precipitation type and amount, station pressure, temperature, dew point temperature, lightning detection elements, and the Frozen Precipitation Sensor Frequency for approximately 900 stations in the U.S., Puerto Rico, the U.S. Virgin Islands, and some Pacific island territories as part of the Automated Surface Observing Systems (ASOS) network. The ASOS Program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD).

This dataset includes five-minute reports with elements for wind speed and direction, visibility, present weather, temperature, dew point temperature, station altimeter, pressure and density altitude, and relative humidity for approximately 900 stations in the U.S., Puerto Rico, the U.S. Virgin Islands, and some Pacific island territories as part of the Automated Surface Observing Systems (ASOS) network. The ASOS Program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD).
