4-D Weather

Weather updates to the cockpit can take many forms and come from a number of sources. Commercial weather providers generally provide value-added National Weather Service products that are currently used operationally. These products are either 2-D graphical or textual. Providers add value to the information by creating graphics from the text, or by decoding teletype formats into readable, plain English text; however, the information content is generally the same. New weather products are gridded, 4-D in nature, so that they can be referenced to a flight profile for planning on the ground or inflight. They also lend themselves to risk management and decision support tool use when a probability or potential for occurrence is added. These new products are being transitioned to operations as part of a defined technology transfer process. Information on the new products can be linked from the left column of this page or see our RAL aviation applications web page.
