![]() The capabilities of aircraft weather radars have steadily grown, and they are now widely available. Some of these systems were adapted for use on the ground. In the 1960s, increased availability of lighter-weight, solid-state electronics made it practical to manufacture a storm avoidance radar for use in commercial and eventually private aircraft. Later the cost and complexity of these systems limited their operational use to government agencies, principally the military and civil weather services however, remote displays from weather radar systems became affordable at airline weather offices, commercial weather services, and broadcast weather facilities. Initially the security classification attached to radar systems of all kinds limited their use to the military weather services. Commercial applications of weather radar could not be covered in the space available Jorgensen and Gerdes (1951) present a good example. Length restrictions prevented addressing the history of the operational use of cloud detection radars, wind profilers, and most other clear-air applications, the exception being the widely used single-Doppler clear-air wind measurement technique. Here we concentrate on the history of application of storm detection radar for operational purposes, such as severe storm identification. Research conducted by operational weather agencies is discussed here, as are research threads that have found their way into operational use or have been of great benefit to operational radar meteorology. Weather Bureau that material is updated and expanded in this paper. (1962) and Bigler (1981) summarize the history and status of the weather radar program conducted by what was then called the U.S. The history of those early developments, and of the research aspects of radar meteorology, is well described in Hitschfeld (1986), Atlas (1990a), and Rogers and Smith (1996). ![]() The use of radar to observe the weather developed as an outcome of the intensive work on radar technology during World War II. The papers are based on the experience of some of those who, at various times, have participated in or led operational weather radar programs. This and the companion paper describe the history of the operational use of storm surveillance radars by U.S. Military applications of radar weather data Education, training, and professional development activities Advances in operational radar data processing and digital applications Use of air defense and air traffic control radars for weather detection Radar reporting code and radar summary chart Acquisition, deployment, and employment of AN/FPS-77 storm-detection radar and interim replacement Expansion of Weather Bureau radar and warning capabilities Acquisition, deployment, and operational use of the first weather radar Post-war use of World War II radars at weather stations First radar networks used for weather surveillance First radar operations at individual stations Its capabilities enable protection efforts of DoD assets around the world. The PDR has directly contributed to the safety of air and ground operations while ensuring mission accomplishment in adverse weather conditions. Products are made available to DoD users and Coalition forces across the globe. Once configured and networked, the PDR also provides Operational Weather Squadron forecasters with critical data to enhance resource protection efforts. These radar systems are utilized by forward deployed weather personnel. Since fielded in August of 2010, the PDR has provided radar products worldwide in environments that previously had no Doppler weather radar capabilities available. The PDR’s technologies grew from the EWR configuration to provide an increase in competency. The EWR was robust and brought new capabilities to Air Force weather support. The PDR is the successor to the Ellason Weather Radar AN/TMS-1 E600. Customizable warning configuration settings.Monitoring of system operating temperatures and faults/errors.Real-time display of Reflectivity, Radial Velocity, and Spectrum Width products with local map backgrounds.Starting and stopping radar scan capability.Map generation capability using onboard GPS coordinates.A 1024 x 756 resolution color display of precipitation and status information.User selected control (direct or remote) via laptop computer running WeatherScout® and Windows.The PDR is a ground-based X-band Doppler radar system. These attributes allow the system to be easily installed and provide precise weather radar data in areas critical for supporting Air Force and Joint Operations. The system is compact, lightweight, and portable. The Portable Doppler Rader, AN/TMS-2 model E700XD, provides real time Doppler weather products with pinpoint accuracy.
