The GARP Atlantic Tropical Experiment (GATE) was the first major international experiment of the Global Atmospheric Research Program (GARP). It was conducted over the tropical atlantic ocean and adjacent land areas under the joint auspices of the World Meteorological Organization (WMO) and the International Council of Scientific Unions (ICSU). The field operations extended from June through September 1974, with headquarters located in Dakar, Senegal.

Radar Plan Position Indicator Scope is the collection of weather radar imagery for the period prior to the beginning of the Next Generation Radar (NEXRAD) system deployed in the mid-1990s. While there are special radar observations in the collection, especially of hurricanes, the primary source of radar imagery in this collection is the weather radar network operated by the U.S. National Weather Service and its predecessor, the U.S. Weather Bureau. This network was deployed in the late 1950s.

Radar Weather Observation is a set of archived historical manuscripts stored on microfiche. The primary source of these radar weather observations manuscript records was approximately 110 National Weather Service (NWS) radar stations. The records were placed on microfiche monthly or annually, depending on the radar station. In addition, the years these records are available vary from station to station. There were approximately 59 NWS radar observing stations equipped with weather surveillance radar which made photographs of the plan position indicator (PPI) scope on 16-mm or 35-mm film.

World Weather Records (WWR) is an archived publication and digital data set. WWR is meteorological data from locations around the world. Through most of its history, WWR has been a publication, first published in 1927. Data includes monthly mean values of pressure, temperature, precipitation, and where available, station metadata notes documenting observation practices and station configurations. In recent years, data were supplied by National Meteorological Services of various countries, many of which became members of the World Meteorological Organization (WMO).

Weighing rain gauge charts record the amount of precipitation that falls at a given location. The vast majority of the Weighing Rain Gauge Recording Charts collection comes from the National Weather Service, cooperative stations, and the Pacific Islands, however, there are some forms that were provided through international organizations and agreements. Throughout much of the history of the collection, observations were taken on paper. However, much of the paper was converted to other media.
