The North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) is an international field experiment with the overarching scientific aim of to increase the physical understanding and to quantify the effects of diabatic processes on disturbances to the jet stream near North America, their influence on downstream propagation across the North Atlantic, and consequences for high-impact weather in Europe. The field campaign will provide a unique observational dataset, sampling the key dynamics and processes associated with the triggering, propagation and downstream impact of disturbances along the North Atlantic waveguide.
A contribution with an aircraft field campaign of HALO and DLR Falcon to NAWDEX is led by the Ludwig-Maximilians-Universität (LMU) Munich and the Deutsches Zentrum für Luft- und Raumfahrt (DLR) Oberpfaffenhofen in cooperation with the Eidgenössische Technische Hochschule (ETH) Zurich and the Naval Research Laboratory (NRL) Monterrey. A successful EUFAR proposal by the University of Reading, UK supports the Falcon campaign.

A more detailed overview of the scientific background and the instrumentation is given in the Campaign Implementation Plan for the deployment of HALO and Falcon in NAWDEX. For the campaign preparation several case studies and a catalogue of forecast products are presented.
