John Hopkins University graduate student Elizabeth Jacobs checks the tension on a cable holding a weather monitoring station in place. For several days in June, she monitored the delta breeze from a field off Hutchison Road west of highway 113 with fellow graduate students Pamela Rawe, Fernando Porte-Agel and Markus Pahlow of from Johns Hopkins University in Baltimore. The experiment is a collaborative venture between Hopkins, UC Davis and the University of Iowa. The students used 12 instruments, oriented to the southwest, that measure the components of wind velocity and air temperatures. "This experimental work is essential to improve our understanding of the turbulent transport of heat and water vapor from the land surface into the atmosphere," environmental engineering graduate student Pahlow explained. His team judged the Davis site on the Campbell tract just what the experiment needed: a flat, homogenous field with a strong wind, blowing from a dominant direction, and a great staff person in tract manager Mike Mata who made the impossible possible for the team's visit, according to Pahlow.
