Outline<\/h3>\n

Field experiments were carried out from the 3rd of July 2003 until the 23rd of July near Hurlock on the Eastern Shore of the Chesapeake Bay in Maryland. The field experiment was carried out in the center of a circular irrigated field of which half of the circle was planted with corn (120 acres). The other half was planted with potatoes.<\/p>\n

\"Fieldtrip1\"<\/a>Exact location of the field site is shown below.<\/p>\n

\"\"<\/a>The aim of the measurements is to determine the distance corn pollen grains are dispersed by wind. Planar PIV measurements were carried out just above and within the corn canopy. Smoke was used as tracer particles.<\/p>\n

Experimental Setup<\/h3>\n

\"ExpSetup1\"<\/a>\"ExpSetup2\"<\/a>Results<\/h3>\n

Mean wind velocity (5 min. averages of streamwise component) obtained from PIV images (Runs 61 to 65) is compared to data obtained from Sonic anemometers and Young propellor windvane at different heights above the ground.<\/p>\n

\"\"<\/a>Mean Velocity profiles of the streamwise component as a function
\nof height are compared to profiles found in the literature.<\/p>\n
