Phase 1 of the world's largest wind-mapping project has begun spinning up in Portugal (link to Nature article). This project, several years in the planning, will culminate with a 45-day intensive measurement campaign in May and June with an intensive observing period. Throughout that IOP, ATOC faculty Julie Lundquist's research group, led by NOAA/CIRES researcher Ludovic Bariteau and several graduate and undergraduate students, will use CU's Tethered Lifting System to measure winds and turbulence within and above the valley; the Army Research Laboratory's identical system will measure winds and turbulence outside the valley for comparison. These detailed in situ measurements will help quantify how turbulence is produced and decays in complex flow situations so that numerical flow models can better represent reality. Other participating teams include University of California Berkeley, University of Oklahoma, the US Army Research Lab, DLR (German Aerospace Center), and the National Center for Atmospheric Research, as well as the teams mentioned in the Nature article from the University of Porto, the Danish Technical University, the University of Notre Dame, and Cornell University
