Summary:
In this work, we have used data from the CBLAST-low2003 experiment, that took
place on the Nantacket island. We preceded data from the sonic anemometer that
was installed at10m height and 90m from the coastline, and was recording at
20Hz. An analytical quality control has been done on the data set (spike
removal, tilt correction, stationarity control) and the false values has been
removed and replaced with linear interpolation. Then using eddy correlation
method, the turbulent characteristic of the flow was found, and Internal
Boundary Layer, Transition Layer, Marine Atmospheric Boundary Layer had been
recognized., using a criterion of the heat flux, and u*. At last quadrant
analysis has been realized, through which we recorded different coherent
structure for the eddies in each layer
