Next week the AEOLEX-II campaign will start! Today we went to the beach to discuss the preferable locations of the instruments. One thing that impressed us all for sure - and what complicated the discussions - is the enormous amount of embryo dunes, and the alongshore variability in their characteristics. At places they had already grown together to give the impression of a new foredune. After discussing the pros and cons of various locations we decided for an array near beach pole 41.000. It is at the northern end of a very wide portion of the beach. We should thus have ample fetch length during the dominant southwesterly winds. At the same time, the embryo dunes have here not yet grown together, avoiding - at least to some degree - their no-doubt complicated effect on air flow and sand transport at the beach-dune transition. A bit further north the embryo dunes were entirely absent, but here the beach looked too narrow and wet to us. Not a good place for a campaign called AEOLEX. Determining instrument positions is always a bit of a gamble, but I am convinced we found the right spot! Also, the FGLab staff carried out the mobile terrestrial laser scanning survey today. Hopefully the survey delivered good data to compare to last-week's UAV-LiDAR data.
