winter summer

weekday weekend

 Operated from summers 2007 to 2009  Results very similar to previous urban turbulence research comfortable that site is well-suited for flux measurements flux data is under renewed investigation  Obtained follow-up funding will commence this summer expand with particle flux measurements
