Displacement Measurement Errors from Moving Platforms

Creator:

Mahrt, L., Vickers, Dean, Drennan, William M., Graber, Hans C., and Crawford, Timothy L.

Abstract:

Errors in eddy correlation measurements from moving platforms (aircraft, ships, buoys, blimps, tethered balloons, and kites) include contamination of the measured fluctuations by superficial fluctuations associated with vertical movement of the platform in the presence of mean vertical gradients. Such errors occur even with perfect removal of the motion of...

Surface stress in offshore flow and quasi-frictional decoupling

Creator:

Mahrt, Larry, Vickers, Dean, Sun, Jielun, Crawford, Timothy L., Crescenti, Gennaro, and Frederickson, Paul

Abstract:

Aircraft data collected at approximately 15 m above the sea surface in the coastal zone are analyzed to examine the spatial distribution of surface stress. Advection of stronger turbulence from land dominates the near-surface turbulence for the first few kilometers offshore. With offshore flow of warm air over cold water,...
