Jun 10, 2016

We now have written access permission from each of the landowners involved, and Cristina Archer has submitted a Wetlands Permit Application Form to the Delaware Department of Natural Resources and Environmental Control for permission to deploy 15 ISFS flux stations in the marsh downwind of the wind turbine

Kurt Knudsen and Steve Semmer are developing a plan for the logistics of deploying and servicing our stations in this challenging environment. Dan Buonome and Gordon Maclean have (almost) the entire complement of sensors and data systems up and running in the EOL staging area.  

Steve has ordered hardware to mount 5 of Cristina’s sonic anemometers and 5 of our hygrothermometers on a nearby 50 m tower in order to characterize the inflow to the wind turbine, while VERTEX co-investigators are providing Doppler Lidar measurements of both the inflow and the turbine wake. 


Project Description: 

VERTEX is a University of Delaware research project led by Cristina Archer to study the effect of the wake of a wind turbine on the atmosphere-surface exchange of momentum, sensible heat and water vapor.

The attached figure shows the array of 15 ISFS flux stations with the wind turbine located in the upper-right of the figure. Station labels indicate the distance from the wind turbine, normalized by D = 2 x blade length = 88 m.
