Winds Aloft is often not accurate and uses time and fuel resources. The Windflow project explores the research question: Could airplanes in flight be employed as a vast sensor network to determine atmospheric conditions? Could data available today be used to infer winds on a large scale without special plane-based wind sensors and new infrastructure to access and combine signals from planes?<\/p>\n<p>Because winds will change an aircraft\u2019s flight path and affect the groundspeed, it is indeed possible to estimate the wind conditions mathematically. However one key piece of data was unavailable: The data provided by the FAA does not include information about where a plane is headed. Solving this conundrum is one of the most significant contributions of this project. Apparently winds exhibit a special property known as spatial regularity\u2014that is, nearby airplanes are likely to encounter similar winds. It is possible to exploit this property by taking observations from nearby wind stations, combining it with the FAA data, and then using a probabilistic model to infer the wind velocity.<\/p>\n<p><b>View the <a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" href=\"http:\/\/windflow.azurewebsites.net\/\" target=\"_blank\" rel=\"noopener\">WindFlow Live Forecast<span class=\"sr-only\"> (opens in new tab)<\/span><\/a><\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Windflow project explores the research questions: Could airplanes in flight be employed as a vast sensor network to determine atmospheric conditions?
